Try FlashBoot for 99% Bootability!
RMPrepUSB can make most USB drives bootable and includes a specially modified version of grubinst.exe, but some older BIOSes may have problems booting from USB devices. I recommend FlashBoot if you need to create an E2B USB drive that will boot on these badly behaved systems.
Please click here to test a time-limited trial version and see if it works for you. How to prepare a Easy2Boot USB drive using FlashBoot
Make_E2B or RMPrepUSB cannot format or write to (WindowsToGo) USB drive.
If a USB drive once held a Windows To Go OS, Windows (10) may lock the drive to prevent you from causing any harm (it 'thinks' that it may have booted from it!).
You may be unable to CLEAN the drive or partition it.
First try selecting FAT32 instead of NTFS (in Make_E2B or RMPrepUSB).
If you are getting Cannot write to MBR errors or Write-protect errors, run diskmgmt.msc, right-click on the USB drive volume coloured bar and choose Delete Volume.
Then try unplugging the USB drive and re-connecting it.
Windows 10 now wants to format my E2B USB - why?
The new Windows 10 Creators Edition (April 2017) appears to have a few new (ahem) 'features'.
It now seems to recognise the 2nd hidden partition on a normal E2B USB Flash drive (removable media) and offers to format it!
You can either cancel the Format pop-up dialogue box each time, or just go ahead and format it to prevent it from popping up every time you insert the E2B USB drive into a Windows 10 system.
The new Win 10 version seems to be able to mount and give drive letters to multiple volumes on USB removable media now, even hidden ones!
Update to the latest versions of E2B and RMPrepUSB to fix these issues when you make a new E2B drive.
Note: If you view the USB drive in the Disk Management Console (diskmgmt.msc), it may not show the 2nd partition as being formatted or as having a drive letter! I guess Microsoft forgot to validate Windows properly before making everyone update!
MPI Tool Kit does not create valid Desktop shortcuts (e.g. MPI_FAT32, MPI_NTFS, etc.)
There seems to be a bug in Windows 10 1607 and later versions, involving VBScript which stops the CreateDesktopShortcut.cmd file and the associated .vbs file from working correctly.
This should now be fixed in MPI Tool Kit version 0.073 and later versions.
'A required CD/DVD drive device driver is missing' (Windows Vista/7/8/10 install ISOs)
This error message normally is seen if your E2B USB drive is not a 'Removable' drive or you are booting Windows Vista/7 from a USB 3.0 USB port. Even if you are using a USB 2.0 port, it may be that Windows does not contain the correct drivers for the USB controller chip if it is a modern PC/notebook.
For Windows 10 TH2 (1511) ISOs, please update your E2B USB drive to the latest version of E2B.
Note that Windows Vista/7 does not contain USB 3.0 drivers, so you must use a USB 2.0 port when installing Windows Vista or 7.
CHECK THAT WINDOWS HAS THE CORRECT USB DRIVER:
1. After booting to Setup, type SHIFT+F10 to open a console window.
2. Type 'diskpart' and press ENTER key.
3. Type 'list disk' - check that your USB drive is listed - if not, then Windows (WinPE) does not contain the correct driver for your USB controller.
4. Type 'exit' to quit diskpart.
See here for how to add the correct USB driver into the ISO file. Ytube video here. Intel driver Win7 ISO patch utility here.
First check that you have the ISOs in the correct sub-folder under \_ISO\WINDOWS (note: do NOT use the \_ISO\WIN folder for Windows installer ISOs).
e.g. a Windows 7 installer ISO would go in the \_ISO\WINDOWS\WIN7 folder that is already present.
You MUST get the blue console window (shown below) when booting Vista/7/8/10 ISOs using E2B. If not then the ISO will not be loaded as a virtual drive and Windows Setup will not be able to access any files inside the ISO (hence the missing driver message).
Blue console window - tis runs ImDisk and loads the ISO as a virtual CD drive
so that Windows Setup can access the files within the ISO file.
There are two types of USB drives, 'Removable' and 'Fixed'. Most USB Flash drives are of the 'Removable' type (RMPrepUSB will display which type it is).
This blue window will only appear if there is a Removable-type of USB flash drive with a \AutoUnattend.xml file on it. Windows only searches for this file on Removable drives.
E2B USB Hard disks (or Fixed-disk type USB Flash drives)
If your E2B USB drive is of the 'Fixed-disk' type, then for Windows ISO files, you will also need an extra 'Removable Disk' Helper USB Flash drive for Vista/7/8 installs, which will contain the \AutoUnattend.xml file. You will need to make and connect this small, removable-type of 'Helper' USB Flash drive and use a Real System (not a VM) if you want to use a USB 'Local/Fixed Disk' type of drive for E2B.
Note: Ensure that the NOHELPER variable is not set in your \_ISO\MyE2B.cfg file. This will prevent the Helper USB Flash drive from working! If in doubt, delete the MyE2B.cfg file and try again.
Alternatively, use MakePartImage to make an image file (.imgPTN) from the ISO. You can then boot from an E2B USB hard disk or Removable disk without needing a 'Helper' flash drive. You can use a VM and you can also boot via UEFI too!
Even if you are booting to E2B from a removable Flash drive using QEMU or a VM such as Virtual Box or VMWare, using a ISO file may not work because any USB drive will appear as a Fixed Disk under a VM and so Windows Setup will not see and 'Removable' USB drive.
Error 60: File is not contiguous or ERROR: XXXX.ISO IS NOT CONTIGUOUS (or is corrupt or missing) - Please run RMPrepUSB - CTRL+F2 or run WinContig.exe to defragment all files.
Why do I get this error?
3. Drag-and-drop the WinSetupFromUSB flash drive letter onto the MPI_FAT32 or MPI_NTFS Desktop shortcut to make a new .imgPTN file from the USB drive (you will need to install the MPI Tool Kit onto your office Windows system)
4. Copy the .imgPTN file to your E2B USB drive (e.g. \_ISO\MAINMENU or \_ISO\WIN)
Note: A .imgPTN file will not work in the \_ISO\WINDOWS\XP folder.
Cannot format drive as NTFS (using Make_E2B or RMPrepUSB), but FAT32 works OK.
Ensure that Windows has assigned a drive letter to the USB drive of between C: and Z:.
Do not use drive letters of A: or B: for the USB drive.
To change the drive letter, type Windows-key+R - diskmgmt.msc - right-click on the drive partition - change drive letter.
Use the latest version of RMPrepUSB and E2B (inc. fix for Windows 10 Creator update).
Try formatting the drive using Windows Format utility as NTFS.
If this also fails, then you probably have a fake flash drive.
Test it using RMPrepUSB - Quick Size Test or FakeFlashTest.exe.
You should always test any new flash memory (USB or SD card) before you use it.
There a MILLIONS of fake drives around!
Why has Make_E2B only made a 130GB partition on my USB hard disk when it is much larger?
If you use the Make_E2B.exe GUI on a USB HDD that is over 137GB in size, it will automatically limit the partition size to approx 137GB (131GiB) in size.
This is because many BIOSes have a serious bug. They cannot access any file past 137GB on a USB drive (using the MBR\CSM BIOS).
You can use the Make_E2B_USB_Drive.cmd button to make a full-sized partition, however you should be aware that on some systems with this 137GB BIOS bug, any file past 137GB on the USB drive will not be accessible by the BIOS. E2B will warn if it detects a buggy BIOS as it boots.
One alternative, is to make a large second partition on the USB HDD.
I recommend using Easeus Partition Master Home Edition (free):
1. Delete the small 2nd partition on the E2B drive
2. Create a new second PRIMARY NTFS partition
3. Don't forget to click Apply or nothing will happen!
You can use the second partition for backup images, etc.
I do not recommend buying Removable USB flash drives that are larger than 128GB.
Windows can only access the 1st partition of a Removable-type USB drive (note: except the Win10 Creator update version!).
This means that the 2nd partition will not be accessible under Windows or WinPE.
How can I tidy up/hide the files in the root of the USB drive?
1. Right-click on the \menu.lst file - Properties - Hidden
2. Now run the E2B download .exe file and click on the Update button (or run .\UPDATE_E2B_DRIVE.CMD from the extracted folder)
This will now hide the files in the root.
From now on, if you update E2B with a later version, the files in the root of the USB drive will remain hidden.
How do I change the Main Menu heading and Footer (F7/F8/F9/F10) Help text to another language?
The Main Menu heading and help text are set in the \_ISO\MyE2B.cfg file.
Use the Sample_MyE2B.cfg as a template for your own MyE2B.cfg file or use the E2B_Editor.exe utility to design your menu.
set HEADING=\x20 EASY2BOOT MAIN MENU (%VER%) %B64% %day%-%month%-%year%
set HELPTEXT=Help [F1] Reboot [F9] Power Off [F10]
set HEADING=\x20 EASY2BOOT MAIN MENU (%VER%) %B64% %@DATE% %@TIME%
set HELPTEXT=Help [F1] Reboot [F9] Power Off [F10]
Help! I accidentally installed grub to the E2B USB drive's MBR. Now it always tries to boot to grub2 or linux!
This might happen if you are installing linux to a partition on the E2B drive and you let it install grub to the MBR (/dev/sdx) instead of /dev/sdx3 or /dev/sdx1.
First install grub4dos to the MBR
RMPrepUSB - Install grub4dos - MBR=Yes (do not copy grldr)
To boot via UEFI, we need to convert each payload to a partition image file (.imgPTN) first.
When you select a .imgPTN file from the E2B menu, it will replace all the partitions on the USB drive with the new partition - i.e. the first partition on the E2B USB drive will now contain the contents of whatever files were inside the partition image file.
How to convert your ISO to a .imgPTN file and UEFI-boot it
First convert your 'payload' file (e.g. ISO) to a FAT32 .imgPTN file using MakePartImage (use the MPI_FAT32 Desktop shortcut provided).
Then copy it onto your E2B USB drive and make sure it is contiguous.
Next, boot from the E2B USB drive in MBR mode as normal and choose the .imgPTN file from the E2B menu system. When it runs it will swap in the payload partition.
Finally, reboot the system from the USB drive in UEFI mode (you should see a 'UEFI: xxx USB drive' menu entry in the UEFI-BIOS Boot Selection menu) - it should now boot to the payload in UEFI mode.
If your system only boots via UEFI and cannot boot in MBR\CSM mode, then you need to MBR-boot the E2B drive in another way first and then switch in the .imgPTN file. You can use the the Windows \_ISO\SWITCH_E2B.exe utility...
Boot the E2B drive using another system that does support MBR/CSM booting
Run the QEMU_MENU_TEST (run as admin).cmd script under Windows
Run RMPartUSB - QEMU (F11) under Windows
Boot the E2B drive using MobaLiveCD.exe under Windows (which uses QEMU) - this is a single .exe file which can be kept on your E2B USB drive
Boot the E2B drive using VirtualBox+VMUB (see here for details)
Boot the E2B drive using VMWare
Boot to WinPE from another USB drive and run QEMU or SWITCH_E2B - see here for details.
Once you have 'switched in' the UEFI image partition, you can connect the E2B drive to your target UEFI system and boot from it.
You can switch the E2B drive back to the E2B menu (restore the E2B partitions) in the same way (use Menu #0 in the CSM Menu or use \e2b\SWITCH_E2B.exe - Restore E2B partitions) - OR - run the \e2b\RestoreE2B (run as admin).cmd file which can be found on the E2B drive or in the MPI Tool Pack folder.
For Win8/10, only specify the name of the XML file, not the full path.
If you are booting from a .imgPTN file, check that you do not have any Removable Flash drive connected (or SD card or Zalman/IODD 'Removable' image loaded which contians a \AutoUnattend.xml or \Unattend.xml file).
I have a fast USB 3.0 Flash drive (e.g. Lexar P20), but it is taking a really long time (an hour+) to make an E2B+DPMS USB drive - why is it taking so long?
Some USB Flash drives have really good read\write specifications for sequential file access (used for large files) but terrible performance for random 4K write accesses (typically used for writing small files).
The E2B+DPMS download contains thousands of small files (XP Mass Storage driver files) and this can cause these inferior performance affects to be seen. Transferring large files may work fine. An example of such a drive is the Lexar P20 flash drive.
A good test is to use 7Zip and extract all files from an XP ISO (approx 580MB which contains 1000+ files) onto the USB drive. Then compare this with the time it takes to copy the large XP.ISO file (e.g. 45 minutes v. 10 seconds!)
Tip: Always use RMPrepUSB - Install grub4dos - MBR=Yes to add the grub4dos boot code to the MBR and following sectors and make the USB drive bootable. Note that 'grub' and 'grub2' are NOT the same as grub4dos!
Alternatively, you can boot to E2B and use the following command:
dd if=(hd0)0+1 of=(hd0)30+1
If prompted, do NOT overwrite the \grldr file with a different version - always use the \grldr file in the E2B download.
I tried E2B, YUMI, XBOOT and none of them boot on my system - why?
If you have a mainboard made after approx 2010, it may be in UEFI-only boot mode. In this mode it will only boot from UEFI boot files.
You need to change the firmware Setup options to enable CSM Mode (sometimes called BIOS or Legacy or MBR mode) and disable Secure Boot.
Symptom: Flashing cursor - no Main menu on some systems, e.g. ASUS M4A89GTD.
If E2B works OK on some systems and QEMU and VBox but not on other systems and you get just a flashing cursor and no wallpaper and no menu displayed, this may be due to a graphics mode problem and grub4dos 0.4.6a compatibility.
Try copying \_ISO\e2b\grub\grldr_045 to \grldr and replace the existing \grldr file. This will make E2B use grub4dos 0.4.5c instead of 0.4.6a.
If it fixes the problem, E2B should still work but .jpg wallpapers will not work and Arabic (right-to-left language) support will not fully work.
This problem can also be caused by the wrong BIOS configuration settings. Ensure it will boot from the USB drive as a 'hard disk' and not as a Floppy drive or ZIP drive. Try different USB boot options.
You can also try formatting the E2B USB drive using FlashBoot. This is a commercial product but you can test it using a trial version first.
During Windows 7 install - no USB mouse\keyboard response.
Windows 7 does not include USB 3 drivers, so make sure you use a USB 2.0 port for your mouse, keyboard and USB drive.
Also look in the BIOS Settings menu for an option to do with 'USB KBC Support' or 'Win7 keyboard support' or 'XHCI support' or other USB options - e.g. DEVICES>USB SETUP>USB VIRTUAL KBC SUPPORT>ENABLED
Another alternative is to add the USB 3 drivers to the Win7 install ISO. Google for 'Win7 USB Patcher' or 'Intel Windows 7 USB 3.0 Creator Utility'.
Tip: I find it easier to boot from any recent Windows Install ISO that supports USB 3.0 (e.g. Win 8.1 or Windows 10), and then run WinNTSetup.exe and install the Windows 7 ISO. There is no need to modify the Windows 7 64-bit ISO if you use this method.
'BIOS BAD!' or 'Checking last sector is accessible...' warning message when booting E2B
This is a BIOS bug, it is not a problem with E2B!
Many system BIOSes have a 137GB (128GiB) USB limit. This bug will affect other multiboot utilities like YUMI, XBOOT, SARDU, etc. too!
E2B checks for a particularly common bug with many BIOSes. Although the BIOS can access all sectors of a large internal (non-USB) hard disk, many BIOSes have a bug in their USB BIOS code which means they cannot access any USB disk sector beyond 137GB. If you have a >137GB USB drive and you see the 'BIOS BAD!' error message, then your BIOS has this bug and your BIOS cannot access any sector past 137GB on your USB drive. Once you boot to a linux or Windows XP+ OS, the BIOS is not used any more and the OS should be able to access all sectors on your drive.
You can press [ENTER] key to continue booting but you may get more errors. If so, again press [ENTER] until you reach the E2B Menu. However, if you have any files that are past 137GB on the USB drive, you may find that they do not work.
You also may find that if you try to use .imgPTN files, they will not 'switch in' or you cannot boot to the CSM menu on systems which have this BIOS bug.
If your E2B drive is less than 137GB, then this error message is probably caused by the last partition on the E2B USB drive extending to the very end of the USB drive. In this case you can either use RMPrepUSB v2.1.730+ to reformat your USB drive (or use the Make_E2B_USB_Drive.cmd script) or simply reduce the size of the last partition on your USB drive by using a free utility such as EaSeus Home Partition Master and move the end of the last partition back by about 1MB or so.
Possible fixes are:
1. Make sure you have the latest revision of BIOS for your system.
2. Use the grub4dos 0.4.6a fast USB 2.0 driver (Utilities Menu). This has it's own USB drivers which will replace the buggy BIOS USB driver (see below for details).
3. You can set CHECKBIOS= in the \_ISO\MyE2B.cfg file to suppress the warning message but this does not fix the BIOS, so some payload files beyond the 137GB position on the disk may fail to boot!
4. Make the first E2B partition <137GB in size (you may still get a warning from E2B but all files in the 1st partition should boot OK)
Fast USB 2.0 driver
To check the BIOS, boot to the E2B Utilities menu - you will see a menu entry 'Install the Grub4dos USB Driver' - run this and if you are using a USB 2.0 port and have a compatible chipset/mainboard, grub4dos will detect your USB device and install the new USB driver which will replace the bad BIOS USB driver. Not all chipsets are suported however.
If the grub4dos USB driver detects the USB drive, then all menu entries should now work (even if the files are situated past 137GB on the USB drive).
You can set E2B to always load the 0.4.6 USB driver my making a \_ISO\MyE2B.cfg file and adding a set GRUB_USB=Y line.
CSM Menu booting
There is no way to fix booting to the CSM menu (when a .imgPTN file is used as a new partition and the .imgPTN file is situated beyond 137GB on the USB drive), because the new partition and the grb4dos \grldr file may be beyond the 137GB point and so the MBR BIOS cannot load grub4dos! You can UEFI-boot using the system UEFI firmware (if that isn't buggy too!), and then use QEMU\VBox\Switch_E2B to switch to the E2B menu when finished.
Keep the E2B files in the first 137GB on the USB disk
If some of the E2B files are situated on the USB drive beyond the 137GB point, then you could try re-making the E2B drive and then copying on your payload files again. Reformatting and then copying over the E2B files in this way will ensure that all E2B files are before the 137GB point. However, if you update the USB drive with a later version of E2B, you may find that some of the E2B files are now beyond the 137GB point again, and it may fail to correctly boot to the E2B menu. If is best to simply use a 137GB partition for E2B and use the spare disk space for another partition to hold your own user files.
Windows XP install from ISO on some DELL systems give 0x0000007B BSOD - why?
Some older Dell systems have a buggy BIOS. First try updating the DELL system to the latest BIOS firmware version.
If that does not fix the issue, modify the XP install .ISO file as follows:
1. Load the ISO file using 7Zip
2. Download the ntd file from the E2B Alternate Downloads Area - Other Files, rename it to ntd.zip and extract the ntdetect.com file
3. Drag-and-drop the ntdetect.com file into the 7Zip \i386 folder to replace the existing \i386\ntdetect.com file
4. Quit 7Zip and save any changes
'ERROR: Required file BOOTMGR is missing!' message when booting a VHD or WIM file.
For copyright reasons, the Easy2Boot download does not contain the Microsoft file 'bootmgr'.
If you see this message when attempting to directly boot an NT6 OS from a .VHD, .VHDX or .WIM file, it means that you need to find a copy of the Windows 8.1 bootmgr file and copy it to the \_ISO\e2b\grub\DPMS\NTBOOT.MOD folder of your Easy2Boot USB drive.
E2B v1.93 and later versions now have a \_ISO\docs\Make_E2B_USB_Drive\Add_Bootmgr_to_E2B_drives.cmd script. Just run this to add the correct version of bootmgr to any connected E2B USB drive.
I added some .ISO or .imgPTN files but they are not detected by E2B and do not appear in the E2B menus - why?
The most common mistake is that you have copied the file to the wrong folder/directory, see here for details.
Windows Installer .imgPTN files should NOT go in the \_ISO\WINDOWS\XP folder. Use any of the other 'normal' menu folder (such as \_ISO\WIN or \_ISO\MAINMENU) for .imgPTN files.
Check that the file extension is correct. If you are using a Windows system, right-click on the file and click on 'Properties' to check the file extension.
.txt, .cmd and files without a file extension will not be added to the E2B menus. If you have a .txt file of the same name - delete it.
Next, did you enable 'FASTLOAD' (does the file \FASTLOAD.YES exist)? - if so, you need to press F8 in the Main Menu to refresh the menu cache file whenever you add or delete a payload file.
Remember that for the ' normal' sub-menu folders, .ISO and other payload files are only auto-detected if they are at the 2nd level (e.g. \_ISO\BACKUP) - they will not be detected at lower folder levels unless you also add a .mnu file.
Tip: Press the SPACE key during file enumeration and it will pause to show you the files and folders that E2B has enumerated. (v1.72+)
Use the E2B - UTILITIES MENU - ls (dir) menu to list files in a menu folder - check the filename and extension is correct.
If you are still having problems, boot to E2B and type SHIFT+P, enter the password (default='easy2boot') and then type SHIFT+C to get to the grub4dos shell console. Now you can look for your file, e.g.
ls /_ISO/WINDOWS/WIN7/ - list files in \_ISO\WINDOWS\WIN7 folder
ls /_ISO/MAINMENU/wi [TAB] - where [TAB] is the TAB key - lists all files beginning with 'wi' in the \_ISO\MAINMENU folder
Check the file extension is listed as expected (note: grub4dos lists spaces in a filename with a preceding \ symbol - e.g. /_ISO/MAINMENU/Spaces\ in\ this\ filename.iso).
Note: It is possible using a .mnu file or .txt file or a .iso64 or .iso32 file extension, to prevent the payload from being listed on 32-bit or 64-bit systems.
It may be that you have too many .mnu files and that you have exceeded the buffer space which E2B uses to store the whole dynamic menu. Try moving some of your payloads and .mnu files to a different menu folder (or create a new menu folder).
How do I update to the latest version of E2B?
Highly Recommended: use the button in Make_E2B.exe GUI - or extract the new version of E2B to an empty, new folder on your Windows drive and run the \UPDATE_E2B_DRIVE.cmd Windows batch file from the new folder.
Otherwise, simply overwrite your existing E2B USB drive with the new version of E2B. You should not have changed any of the original E2B files, so overwriting should not undo any of your changes. If updating from E2B v1.5x to 1.6x or later, remove all old \_ISO\MAINMENU\ZZ*.mnu file so that only ZZSubMenuAll.mnu and the ZZGRUB_USB_046.mnu menu files are left - otherwise you will get multiple Main menu entries).
If you have edited any of the original E2B files (which you should NOT do!) then you will need to use a utility such as WinMerge to see what changes have been made.
Note: Unless the Mass Storage Driver Pack drivers have been updated (check the revision history), you only need to update using the smaller non-DPMS E2B download file, even if your original E2B drive was made from the larger E2B+DPMS download.
Tip: You can run "\_ISO\docs\Make_E2B_USB_Drive\CheckForUpdate.cmd" to check for a more recent version of E2B.
Why does Windows 8/8.1/10 prompt me for a Product Key when installing from an ISO?
This is usually because you have not selected the correct Product Key when asked to by E2B before Setup starts to run. e.g. A Windows 8.1 Pro Retail\OEM ISO requires a Win8.1 Pro Retail Product Key. A Windows 8.1 Pro Volume Licence ISO requires a Win 8.1 Pro Product Key.
Typically, a Retail ISO will contain multiple editions (e.g. Core and Pro). Some other versions (e.g. Enterprise or VL versions) may only contain one Edition.
Some Windows Install ISOs do not normally require a Product Key to be entered by the user when instaling from a DVD. However, when using E2B and installing from an ISO, you still need to specify the 'internal' Product Key. If you do not know the 'internal' Product Key, then install Windows using the DVD (or perhaps from a USB drive made using Rufus). When the install is finished, used an application like ProduKey or Magical Jelly Bean Key Finder to reveal the internal Product Key. Then use that same Product to install from the ISO using E2B.
How do I change the menu position, colours, headings and background wallpaper, etc.?
To use your own wallpaper image, copy your own mybackground.bmp or mybackground.bmp.gz file to the \_ISO folder (you can compress a .bmp to a .bmp.gz using 7Zip and by selecting gzip as the compression type – this greatly reduces the file size).
To use a background image of a different name or location, copy the configuration file \_ISO\Sample_MyE2B.cfg file to \_ISO\MyE2B.cfg. Change the MyWBMP entry to the location of your background file. See here for more details. The MyE2B.cfg file also allows you to change the default text colours, menu size and position (and lots of other things too!)
To change the background wallpaper in the CSM menu of a partition image file, make a new 800x600 bitmap (it can be compressed to gzip format) and name it csm.bmp.gz . Place the file in the MakePartImage\CUSTOM\e2b folder on your Windows system. When you next make a .imgPTN file using MakePartImage, the new bitmap file will be used. For more details on how to change the CSM menu (text colours, menu position, etc.), see here.
How do I get a 'special' ISO to work!
If there is a specific ISO or payload that you cannot get to work, or you want to alter E2B in some way...
Make sure you press SCROLL LOCK to light the LED before you select the ISO - this will force E2B to show you suggested file extensions when you run the ISO
Search this site for the name of the payload/ISO (e.g. 'ubuntu')
Check in the list of tested payloads here and also use the Site Map (signpost icon)
Check the Sample .mnu Files list here (and check the \_ISO\docs\Sample mnu files folder of your E2B download)
Windows 7 and SVR2K8R2 64-bit Installer will not UEFI-boot as FAT32 .imgPTN file (Win8/10 work OK)
Special instructions for Windows 7 64-bit UEFI booting here.
The ISO does not contain the correct boot file, it only contains the CD boot file \EFI\boot\cdboot.efi which is not used when booting from a disk. To fix this
1. Make a .imgPTN file from the Win7 64-bit install ISO using the MPI_FAT32 shortcut
2. Switch to the .imgPTN file using the E2B menu (e.g. using \QEMU_MENU_TEST (run as admin).cmd or real system)
3. Connect E2B drive to a Windows\Linux system so you can access the files
4. Move the \efi\microsoft\boot folder up one level into the efi folder as \efi\boot (see piccy below).
5. Using 7-zip, open the original ISO and navigate to the \sources\install.wim - 1\Windows\Boot\EFI\bootmgfw.efi on the E2B USB drive, select the bootmgfw.efi file, copy it to the \EFI\boot folder on the E2B USB drive.
6. Rename \EFI\boot\bootmgfw.efi to bootx64.efi
1. Use RUFUS to create a FAT32 (not GPT) UEFI-bootable flash drive
2. Drag-and-drop the USB flash drive letter onto the MPI_FAT32 Desktop shortcut to make a .imgPTN file
3. Copy the .imgPTN file to your E2B USB drive
'The file 'Asms' on Windows XP CD-ROM is needed' error after Step 2 of XP Install
The file 'Asms' on Windows XP Professional CD-ROM is needed. Type the path where the file is located, and then click OK.
If you see the error message from a Windows XP install from ISO after choosing Step 2 from the Easy2Boot XP install menu, please ensure you are using E2B v1.51a or later. There was a bug in v1.32-1.51.
This error means that XP is unable to find the source installation files which it expects to find in the \i386 folder of the installation device. In the case of running from E2B this can mean that FiraDisk was unable to access the USB drive and load the ISO as a virtual drive.
You will know if the ISO is loaded into RAM because it will take a minute or two to load before it starts to boot from the hard disk into the GUI mode of XP Setup. e.g.
Loading XOPROSP3.ISO into memory - please wait...
Tip: If you are still getting a 'missing file' error - try disabling the CD-ROM/DVD-ROM in the BIOS Setup menu before installing XP.
Installing from an XP Install ISO is not working on some systems. I have tried all combinations. Booting using YUMI\Rufus\WinSetupFromUSB works OK.
Ensure you are not using USB 3.0 ports. If you have tried loading the ISO into memory and tried the 1, 2 and 3 DPMS options for Firadisk\WinVBlock, then there is probably some USB/reset/chipset incompatibility. Installing direct from an ISO does not always work on some systems - it is not as reliable as a 1-step process but in order to install direct from an ISO, two USB boot steps are required.
If you have made a USB Flash drive that does install XP using some other method, e.g. Rufus or YUMI or WinSetupFromUSB (which also uses the DPMS2 code from E2B and is recommended), then make an image of that USB Flash drive using MakePartImage. Watch the YouTube videos on MakePartImage to see how to install it. Then just drag-and-drop the USB Flash drive icon that you want to make an image from, onto the MPI NTFS Desktop shortcut. Then copy the image to your E2B USB drive and run WinContig on it.
Note: Use the latest version of E2B. This blog post may help.
Tip: If you are getting a 'missing file' error - try disabling the CD-ROM/DVD-ROM in the BIOS Setup menu before installing XP.
Note that E2B v1.92+ contains a bug fix for AMD chipset drivers for XP.
How do I add Windows 7/8/10 ,etc. Install ISOs?
Copy the ISO to \_ISO\Windows\xxxx folder, e.g. \_ISO\WINDOWS\WIN10 folder for Windows 10 Install ISOs.
For UEFI booting, make a partition image of the ISO using MakePartImage. Note: Special attention is required when converting a Win7 64-bit ISO to a .imgPTN file for UEFI-booting.
Windows 10 does not normally require you to specify a Product Key, so you can use the NO KEY (choose a version to install) option. If you do select a Product Key, it MUST match the version of Win 10 that you are installing or you may get a 'License error'.
XP\Win7 do not have USB 3.0 drivers, so use USB 2.0 port or see here.
E2B will work using standard Microsoft Windows Install ISOs. Some modified All-in-One ISOs may not work as a .ISO file - in this case, convert the ISO to a .imgPTN file.
How do I add a Windows 8/SVR2012 Installer ISO?
Copy the ISO to the \_ISO\WINDOWS\WIN8 folder.
IMPORTANT: Many Windows 8/SVR2012 Install ISOs require a Product Key when using E2B (even if they don't normally ask for a Product Key).
Ensure that you know what the Product Key is and then select the correct one from the menu when asked by E2B. You can add more Product Keys to the menu - look at the .key files to see how to add the Product Key you need for your ISO.
If you use the wrong Product Key, you can get all sorts of errors such as incorrect licence, etc.
For UEFI booting, make a partition image of the ISO using MakePartImage.
How do I add a Hirens Boot CD ISO and get it all working?
How do I get rid of the sub-menu entries that are listed in the Main menu (e.g. UTILITIES)?
Simply ensure that the \_ISO\BACKUP, \_ISO\BACKUP_LINUX, \_ISO\DOS, \_ISO\UTILITIES and \_ISO\UTILITIES_MEMTEST folders are empty (no sub-folders or files)
Help! I ran .imgPTN file and now I can't get the E2B menu back or even boot to the CSM menu!
Boot the E2B drive in MBR mode using QEMU (you can use RMPrepUSB and press F11 to boot it or use a real system) and then select the 'Easy2Boot menu - switch' option from the CSM menu.
If you don't see the CSM menu at all (it doesn't boot or just boots to the payload that was in the image) then run SWITCH_E2B.exe or 'RestoreE2B.cmd' under Windows, which you will find in the MakePartImage download and also on the E2B drive (in the \e2b folder if present). This must be run as admin from your Windows system.
If this happens on some systems but not all systems, re-make the .imgPTN file using MakePartImage v0.027 or later. Try also renaming the .imgPTN file to .imgPTN23A.
N.B. Some UEFI systems will not offer the user a MBR\CSM boot option if there are UEFI boot files present on the USB drive. This means that after changing to an .imgPTN file which contains EFI boot files, you may not be able to boot to the CSM Menu and restore the drive back to the E2B menu. For these systems, you must either MBR-boot on a different system, or use a Windows system to run \e2b\SWITCH_E2B.exe to restore the E2B partitions.
How do I add YLMF/Ubuntu/Fedora/StartOS/Porteus/pclinuxos/Backtrack5/kali-linux ISOs and have persistence?
Read the help text inside the relevant .mnu file in the \_ISO\docs\Sample mnu files folder.
Persistence - I have used a .mnu file for persistence with a linux ISO, but I don't get persistence.
You MUST run WinContig after preparing the USB drive and making the ext2 file - all files including the ext2 file need to be contiguous.
Check that you have created the ext2 file according to the instructions in the .mnu file (use the latest RMPrepUSB version 2.1.711+ which allows you to set the file name and volume name separately). Check the file name and the volume name are correct - you can edit\change the ext2 filename but do NOT change the name of the Volume name from the one specified in the .mnu file.
How do I add the ERD Commander 2005/2007 or MSDaRT 5 (XP) Recovery ISOs?
Try the .isomemF01 file exension
Copy the ISO file to (for example) \_ISO\UTILITIES\Dart5 folder and also the ERD2005.mnu file. Copy, read and edit the ERD2005.mnu file (which can be found in the \_ISO\docs\Sample mnu files folder) for more details.
For best results or if your target system has a SATA hard disk, use the DPMS2 version of E2B and the ERD5_DPMS.mnu sample menu. This allows you to repair an XP system containing SATA or RAID hard disks, even if the ISO does not contain suitable drivers!
How do I get ERD/MSDaRT 6-8.1 for Vista\Win7\Win8 working?
Rename to .iso01 or use .isoPE01 to also mount the ISO file as a drive letter.
If using .isoPE01, you will need to have E2B on a Removable USB flash drive or also have a E2B Helper USB Flash drive connected. This will ensure that the ISO file is loaded as a virtual DVD when it boots to WinPE.
If you require UEFI booting of MSDaRT, use MakePartImage to convert the ISO into a partition image file - see here for details. This also avoids having to use a Helper USB Flash drive.
Some systems do not give a UEFI boot option when using a working FAT32 .imgPTN file, but other systems can boot via UEFI from the same file - why?
This may be due to the UEFI firmware not 'liking' the partitions that it sees once you have switched to the new .imgPTN file. The UEFI specification is not very precise and so some manufacturers can interpret it differently. Also it may just be a bug in the firmware on that system (see if there is a later BIOS update available from the manufacturer).
First try selecting the .imgPTN file using both the E2B Menu system (by MBR-booting) and then try again by using the SWITCH_E2B.exe utility. Check if they both give the same results (if not please Contact Me with the details).
Next, try experimenting with different file extensions for the .imgPTN file - e.g.
If you find this fixes the problem, again please Contact Me with the details, so I can tweak the next version!
When I boot my E2B USB drive on some systems I get an error - but on other systems it boots OK - why?
This is usually due to a 'bad' BIOS. First check if there is a more recent BIOS for that system on the manufacturers web site.
Next, check the BIOS settings to make sure it is booting the USB drive as a Hard/Fixed Disk. Also check that your BIOS Setup menu is set for Legacy/CMS mode and not UEFI mode.
If the 'check last sector' test is causing a problem, reformat using RMPrepUSB v2.1.714 or later. If necessary, you can just delete the \_ISO\E2B\grub\checkaccess.g4b file (but be aware that the BIOS is still bad and so you may get other problems!).
Update to the most recent version of E2B.
Can I use Plop with E2B if my system does not support USB booting?
Short answer = No (not easily)!
You can boot from a CD containing Plop and then choose the boot from USB menu option in Plop to boot from the E2B USB drive, even if your system is not capable of booting from a USB drive directly.
However, Plop contains a read-only USB 2.0 driver that does not support writes to a USB device.
As most functions of E2B (e.g. boot from ISO) involve writing to the E2B boot drive or E2B helper Flash drive, writes need to be supported for E2B to work it's magic.
Therefore, if you boot to Plop and then try to run an E2B menu entry, you will probably see a 'write error' message. However, if you use grub4dos 0.4.6a (standard in v1.62+ or a menu entry older versions), you can boot to E2B from Plop and then use the - Utilities - Install fast grub4dos usb 2.0 driver menu entry. The grub4dos USB 2.0 driver has full rd/wr support and after the USB driver is loaded, E2B should work as normal (until you reboot).
Tip: When you select the USB Boot option in Plop, hold down the SHIFT key first, before pressing ENTER. This will cause E2B to load the grub4dos USB 2.0 driver (E2B v1.91+).
Unfortunately, the grub4dos USB 2.0 driver has limited USB controller support and may not work on many modern systems!
You can also try the USB_BOOT CD/ISO instead of Plop on a CD - see my blog post here.
How can I change the order of the menu entries listed in each E2B menu?
All items (files and folders) are sorted alphanumerically. Just rename the 3rd level folders, 2nd level payload and the .mnu files.
Use Windows Explorer to sort the files by name (click on the top of the Name column in Explorer) and that will be the order that the files will be listed in, in the E2B menu.
E2B enumerates all payload files in the 2nd level folder and .mnu files in all folders: e.g. if you have files in folders $$FRED and FRED, this will be the menu order when they are alphanumerically sorted by E2B:
Note that sub-folders are sorted by name, together with payload files and .mnu files. You may need to change the name of the subfolder (e.g. change \_ISO\MAINMENU\MNU to \_ISO\MAINMENU\$MNU) to make the menu entries list in a different order.
ZZSubMenuAll.mnu contains many Main menu entries in a pre-set order - if you want to change the order of these, then rename the file (e.g. rename to ZZSubMenuMe.mnu) and then edit it to change or modify the menu entries or their order.
Can I use E2B on my Zalman VE200/300/400 DVD emulator drive?
Yes. Install grub4dos using RMPrepUSB and add the E2B files. See this section for details of how to avoid having to rename iso file extensions. When booting E2B, the Zalman will be seen as a Fixed Disk and so you will need a USB 'Helper' flash drive for some functions (e.g. Windows 7/8 Install isos).
There are lots of possible extensions that E2B supports for .iso files - how can I find out which one is best for my iso?
First search this page for the name of your particular version. There is a list of the different possible file extensions here.
Press SCROLL LOCK before you select the ISO file in the E2B menu to see suggestions.
If you are still having problems, name your .iso file as .isoask - you will then be prompted by E2B and asked how you want to run the .iso file. Once you find an extension that works, rename the file to whatever file extension worked best.
E2B may suggest you try .isoask and prompt you - answer I quickly and press ENTER and E2B will display the .isoask menu for you.
To avoid being prompted, use the .isodefault file extension.
WinBuilder ISOs require a .iso file extension. If the filename ends in q or Q, the auto-suggest prompt will be suppressed - e.g. Gandalf_q.iso.
How do I get my WinPE ISO (e.g. WinBuilder) to see the ISO as drive letter Y: ?
E2B USB Flash drive won't boot on one particular system
Try installing a Standard MBR using the RMPrepUSB - BootLoaders tab and installing grub4dos only to the PBR. If that doesn't work, try preparing a USB flash drive using flashboot - see Tutorial 113 for details.
If the problem is with .imgPTN files, try renaming them as .imgPTN23LBAa instead.
See the 'Some systems do not give a UEFI-boot option...' FAQ if it is a UEFI boot problem.
On older systems, you may have more luck using FlashBoot with E2B - see the box on this page for a link and a tutorial.
Error from .cmd script: 'Sorry - you need to run as Administrator [use right-click - Run as administrator].'
If you see this message, then the .cmd script thinks that you are not running with Administrator privileges.
1. Open an Administrator command shell and type:
If this fails to run correctly, then you may have a problem with your Windows system which you need to fix!
2. Open an Administrator command shell and type:
If you get 'access denied' then there is some sort of access problem with your Windows folder which you need to fix!
'Setup was unable to create a new system partition or locate an existing system partition.' (Win7/8/10 error message)
Ensure the BIOS boot order has the internal hard disk as the first disk (do not set the E2B USB boot disk as the first disk in the boot order).
Then use the BIOS Boot selection menu (e.g. F8 or F11 or F12 or F10) to select the E2B USB drive to boot from. Remove any SD cards or other unnecessary storage devices. See here for a discussion. Ensure the internal hard disk has an active (bootable) partition.
If the internal hard disk has previously been formatted as GPT, you may need to use Diskpart - CLEAN and CONVERT MBR on it first.
With Windows Vista/7/8/10 install ISOs, I don't get prompted to select a language?
This has probably been suppressed because E2B has to use an xml answer file. You may need to add a 'WillShowUI' section and make a new .xml file. Place it in the same folder as the Windows ISO. See here for an example file. Try selecting the Full_Language_UI.xml file (see \_ISO\WINDOWS\WIN7 folder for an example file).
You can also create an unattend.xml file to specify the exact language and country settings that you want and even fully automate the install - see here for more information.
error 13: invalid or unsupported executable format
This usually means your payload file (.ISO, .IMA, etc) was not bootable or it is corrupt. Some Windows ISOs are upgrade CDs or DVDs and are not bootable - they are designed to run from within Windows.
If you made the ISO yourself - do not use Joilet format and make sure you add in the boot sector code to make it bootable - see here for more details.
'File caused an unexpected error(0) at line 2166 in d:\xpsp\base\boot\setup\oemdisk.c. Press any key to continue'
ERROR: /_ISO/CONTIG.ISO is smaller than xxxxx.ISO - Cannot copy!
The default \_ISO\CONTIG.ISO is 500MB in size. E2B can use the dd command to copy the contents of a non-contiguous ISO to CONTIG.ISO (which needs to be contiguous). This error message means that the ISO you want to boot is larger than CONTIG.ISO and so cannot be copied.
You can replace the CONTIG.ISO file with a larger file (of any type, any contents) and just rename as it as CONTIG.ISO. Then run WinContig to make sure the new CONTIG.ISO is contiguous.
Bear in mind that larger ISOs will, of course, take longer to copy into CONTIG.ISO.
How can I have just one (empty) Main menu?
Make sure the menu folders (\_ISO\DOS, \_ISO\UTILITIES, etc.) are completely empty.
Make sure the \_ISO\WINDOWS\xxx folders (e.g. \_ISO\WINDOWS\WIN7) do not contain any ISO files.
If you don't want the 'Set default menu and timeout' menu entry, add this line to \_ISO\MyE2B.cfg (file must start with !BAT):
Note: You can disable the F1 help, F7-F10 menu entries individually by using settings in your \_ISO\MyE2B.cfg file.
You can also prevent the Windows menu from being listed + many other options too.
There are examples of various MyE2B.cfg files in the \_ISO\docs\MyThemes folder.
E2B reports file is not a .imgPTN file or not contiguous, when I try to run a .imgPTN file.
If E2B reports that the file is not a .imgPTN file or displays ERROR 60: file not contiguous or corrupt - run WinContig on the drive (RMPrepUSB - Ctrl+F2) to make all files on the drive contiguous or run the \MAKE_THIS_DRIVE_CONTIGUOUS.cmd batch file. This works on the first partition of the USB drive only.
If your USB drive has more than one partition and the .imgPTN file is on the second partition, run WinContig.exe manually and select the partition to 'defrag'.
The menu is slow to load - how can I speed it up and make it faster?
Note: Some USB Flash drives seem to have a problem with some system's BIOSes and are very slow - e.g. Emtec USB 3.0 Color Mix and Mushkin Flash drives. If possible, try a different make or model of USB Flash drive and also try a completely different computer.
If it takes a long time to display the Main Menu, then your BIOS probably has very poor USB drivers. It does not matter how fast the CPU is - it is the BIOS's USB code that is causing the slowness (or maybe some other USB device)! Known slow systems are: Asus P5E-VM, AMI BIOS MSI K9N Neo, Shuttle SD30G2 Core2Duo with Phoenix-Award BIOS, Shuttle SK21G, Dell GX260, Lenovo R51, systems with AWARD V6.00PG BIOS.
Tip: (E2B v1.91+) - press and hold down the SHIFT key just before E2B starts to boot. This will cause the grub4dos USB 2.0 driver to load which may result in much faster performance and also fix any BIOS 137GB limit bug.
In the Utilities menu you can find a Measure USB Performance menu entry - 100 loops should take between 1 to 5 seconds. If it takes much longer than this, your BIOS has very bad USB driver code! Some bad BIOSes can take over 40 seconds!
Try grub4dos 0.4.6a with it's own USB 2.0 driver to replace the BIOS USB driver. To do this, use the 'Install the Grub4dos USB driver' menu entry in the Utilities Menu (or hold down the SHIFT key just before E2B boots). If the driver successfully detects a USB device then try the Measure USB Performance test again to see if it is faster.
To always enable the Grub4dos USB driver use set GRUB_USB=Y in your \_ISO\MyE2B.cfg file to permanently enable it (not recommended).
It is a USB 2.0 driver and may not work on all systems with USB 2.0 ports however.
Use a fast USB 3.0 drive if possible (even if you only have USB 2.0 ports). Slow USB 2.0 Flash drives can drastically affect the time it takes for the Main menu to appear. USB 2.0 card readers are notoriously slow!
You can delete any .mnu or other files in the \_ISO\MAINMENU folder that you don't need or move payload files to sub-menu folders.
Create more sub-menu folders using the \_ISO\docs\E2B Utilities\E2B SUBMENU Maker.cmd script and distribute your ISOs amongst these folders - e.g. \_ISO\CLONEZILLA, \_ISO\OPHCRACK, etc. A Menu will take longer to display if the menu folder contains lots of payload files.
File enumeration is much slower on NTFS E2B partitions (takes twice as long as FAT32 or exFAT) - so if possible, format your E2B drive using FAT32 if you have a slow USB drive.
You can pre-cache the Main menu by using the E2B 'Fastload' feature. Just copy the FASTLOAD.YES file (found in the \_ISO\docs\FASTLOAD folder) to the root of your E2B drive. After the first boot, the Main menu will be stored on the E2B drive. When you boot again, the menu contents will be read from the store. If you add another ISO to E2B \_ISO\MAINMENU folder, it will not show up in the Main menu until you reload the Main Menu (press F8).
If you are using a USB 'Removable-type' Flash drive then you will never need to use a 'Helper' USB Flash drive for Windows Vista/7/8 installs or for WinPE ISOs, so use the 'set NOHELPER=1' setting in your \_ISO\MyE2B.cfg file to tell E2B not to look for one during start-up.
If you have lots of files in the \_ISO\MAINMENU and lots of Windows Install ISOs in \_ISO\WINDOWS\xxx folders, then the Main menu can be slow to load on a slow USB Flash drive. Delete or move all uneccesary files from the \_ISO\WINDOWS\xxx and \_ISO\MAINMENU folders and sub-folders (e.g. the empty 'hint' files with no file extension, ReadMe.txt files that are in the E2B download, any .mnu files that you will never use, .key and .xml files that you don't need, etc.). Files in the non-menu folders (e.g. \_ISO\docs) will not affect performance.
Try the TextMinimal MyE2B.cfg file (copy it from \_ISO\docs\Sample E2B Templates\TextMinimal to \_ISO). This suppresses loading of the large unifont file and bitmap wallpaper. This can save 10 seconds or so on a very slow system. Or, as a test, add these lines to a new \_ISO\MyE2B.cfg file:
Tip: Add a new xxxx.cfg file to \_ISO\MAINMENU containing MyE2B.cfg settings (e.g. copy the Sample_MyE2B.cfg file to \_ISO\MAINMENU\GraphicsMode.cfg), then you can 'switch' to a graphics mode with a wallpaper once the Main menu has loaded in text mode if you have a fast system.
You can also use a plain coloured background instead of loading a large bitmap, by setting the wallpaper colour in the MyE2B.cfg file: e.g. set MYWBMP=0xCC77EE
File extension is .imgPTN - ERROR: No Grub4dos installed to MBR of this drive! I get this error when running every .imgPTN file -why?
To run .imgPTN files, you need to install grub4dos to the MBR (first sector) of the USB drive.
It is easy to fix. Just run RMPrepUSB, select the USB drive and click on Install grub4dos - and choose YES=MBR when asked.
This will install the grub4dos boot code to the MBR of the USB drive. Be careful not to overwrite the \grldr file with an older version though!
Flashing cursor or no CSM menu when re-booting to a .imgPTN image file on some systems
If most systems boot successfully from a .imgPTN partition image file (including booting using RMPrepUSB - QEMU), but one type of system does not and you just get a flashing cursor, re-make the .imgPTN file using MakePartImage v0.027 or later. Also try renaming the file extension to .imgPTN23A. Ensure that a small 2nd partition is present (check using RMPrepUSB - Drive Info - 0). If you have a 'BIOS BAD' message on booting E2B, make sure all files are below the 137GB point on the USB drive (or reformat/resize the E2B partition to be 137GB).
Booting from a .imgPTN file on some systems gives a 'Missing MBR Helper' message and won't boot.
If you get a 'Missing MBR Helper' message when booting in MBR mode from a .imgPTN file on some systems, rename the file to .imgPTN23LBAa
How can I boot E2B to a UEFI image without needing to boot to MBR mode first?
My E2B USB Hard Disk is not listed in the BIOS boot menu?
If you are using a USB Hard Disk, this may be a detection issue. Look for a Hard Disk delay option in the BIOS Setup Menu and set it to 5-10 seconds.
Otherwise, when you get to the BIOS Boot Selection (BBS) menu, press CTRL-ALT-DEL to reboot and try again.
Different systems/models use different HotKeys for the BBS Menu:
Asus F8 or ESC, Sony F2, GateWay F10, Gigabyte F12, Dell F12, HP/Compaq Esc, Acer F12, eMachines F10, Toshiba F12, Fujitsu F12
Note this list is a guide only - different models may use a different hotkey!
Check you BIOS options for Secure Boot = Disable and CSM\Legacy boot mode = Enable.
Also note that many BIOSes require you to hold down the Fn key and then press the correct F key - there is often a BIOS option setting to enable\disable this very annoying feature!
I have a large All-in-One (AIO) Windows Installer ISO - how do I add it to E2B?
If your E2B USB drive a 'Removable-type' USB Flash drive, add the ISO file to one of the E2B menu folders (e.g. \_ISO\MAINMENU or \_ISO\WIN) and rename the file extension as .ISOpe01. If your USB drive is of the 'Local\Fixed Disk' type, then you will also need to connect a USB 'Helper' Flash drive (any size). Your E2B drive obviously needs to be formatted as NTFS to hold large files.
If this fails to work, convert the ISO to a .imgPTN file (see below).
If your AIO ISO supports UEFI-booting or you don't want to use a 'Helper' flash drive, use MakePartImage to make a FAT32 partition image from the ISO. Then add the file to your E2B drive (e.g. \_ISO\MAINMENU or \_ISO\WIN) and rename the file extension as .imgPTNLBAa). You should now be able to boot to the image and install in both MBR and UEFI mode (if Clover is in the image, you can boot via Clover straight to UEFI mode).
In order to hold .imgPTN files that are larger than 4GB, you will need to make your E2B USb drive using the NTFS filesystem.
Note: Even if you ISO is larger than 4GB, as long as no file inside the ISO is larger than 4GB, you can convert it to a FAT32 .imgPTN file (the E2B volume needs to be formatted as NTFS).
.imgPTN image partition file won't boot on one type of system (e.g. EeePC) - grub4dos 'hd0,0 non-MS' is displayed briefly.
It may be due to a 'bad' BIOS. Is the .imgPTN file on a large hard disk and past 137GB? Does normal booting to E2B give you warnings about a BAD BIOS? If so there is not much that can be done. The grub4dos grldr file is located beyond the 137GB point and the BIOS has a USB disk-access bug and cannot access blocks past 137GB.
To fix, erase and reformat the whole USB drive and copy the E2B and .imgPTN files on first so the important image files are before 137GB on the disk. Files that you only boot to using E2B - e.g. ISO files, can be added after these. If you later try to add another .imgPTN file, make sure it is below the 137GB point, otherwise you will need to reformat and re-copy the .imgPTN files on first again!
If you have ISOs which are located beyond 137GB, use a USB 2.0 port and load the grub4dos USB 2.0 driver in the Utilities Menu before running the ISO file.
Some ISOs that I converted to .imgPTN files won't UEFI-boot - why not?
If some .imgPTN files successfully UEFI-boot but others do not, then it may be due to a number of reasons:
1. You must make a FAT32 .imgPTN file (e.g. use the MPI_FAT32 desktop shortcut). Do not use the MPI_NTFS shortcut because most UEFI systems cannot read NTFS partitions.
2. The ISO/payload does not support UEFI-booting. This is easy to spot. When you select the .imgPTN file in the Easy2Boot menu, it will list the .efi boot files that are present. The CSM menu also lists the UEFI .efi boot files. These are \EFI\boot\bootx64.efi for 64-bit UEFI systems and \EFI\boot\bootia32.efi for 32-bit UEFI systems. If these are not present in your ISO\payload then they do not support UEFI-booting. E2B and the MPI Toolkit cannot make a non-UEFI payload into a UEFI-bootable payload - it has to be UEFI-bootable and contain one or both of these UEFI boot files in the original ISO\payload.
3. The UEFI system you are trying to boot with is not the correct type and your UEFI payload only has the 'wrong' type of efi boot file.
x86 32-bit UEFI firmware will only UEFI-boot from the \EFI\boot\bootia32.efi file
x86 64-bit UEFI firmware will only UEFI-boot from the \EFI\boot\bootx64.efi file
Note: Even though a system may contain a 64-bit CPU, the firmware may be a 32-bit UEFI version and thus only boot \EFI\boot\bootia32.efi files (e.g. Asus T100).
A few ISO\payloads contain both 32-bit and 64-bit UEFI boot files (e.g. Clonezilla and Parted Magic).
How can I get persistence to work with .imgPTN files
You can fully install linux to a .imgPTN partition image file, or in some case, add persistence files.
How can I make E2B auto-boot to the internal hard disk after installing Windows Vista/7/8.
It is always preferable to use the computer BIOS Boot Selection menu popup box (usually obtained by pressing a Fxx key or the ESC key) than to preset the boot order in the BIOS. However, if a BIOS boot option popup menu is not available, you can proceed as follows:
make a $$$$BootHdd.mnu file so that the Boot to HDD menu entry will always be number #1
title Boot to internal Hard Disk 0\n
map (hd0) (hd1) && map (hd1) (hd0)
Boot to the E2B menu and select menu item 0 Set default menu entry and timeout
Set the Default Menu Item to 1
Set Menu timeout in Seconds to 10 (or whatever you prefer)
(Optional) Supress the F7 menu entry by adding set NOF7HD=1 to the \_ISO\MyE2B.cfg file
Now you can install Windows Vista/7/8 and when the system reboots, it will reboot to the internal hard disk after 10 seconds unless you press a key to stop the timeout.
Can I boot Windows from my E2B USB drive?
You can have one or more WindowsToGo installations on the same E2B USB drive. See my blog post here.
You can also boot from .VHD and .WIM files too - see blog post here.
What other languages are available for E2B other than English?
Supported languages can be detected by looking for their folders \_ISO\e2b\grub (e.g. ENG) - language folders will have a STRINGS.txt file in them.
You can copy the \_ISO\docs\Change_Language.mnu file to the \_ISO\MAINMENU folder to get a menu entry which will allow the user to temporarily change the language.

What is CONTIG.ISO? Why is it taking so long to run the ISO?
\_ISO\CONTIG.ISO is used by E2B to make an ISO file contiguous if it is not already contiguous. It is optional and you can delete it if you want to save 500MB of filespace.
e.g. If \_ISO\MAINMENU\fred.iso is not a contiguous file, E2B will copy the contents of the file to CONTIG.ISO (if it is contiguous) and then boot from CONTIG.ISO.
If you always make sure that all your files are contiguous on the E2B drive, you can delete the CONTIG.ISO file and save space. It will also cut out the long file copy time too!
If you have non-contiguous ISO files that are larger than CONTIG.ISO, E2B will warn you and will be unable to defragment the file. To fix this, just copy a larger file (any type) to \_ISO and name it CONTIG.ISO. Obviously, large ISOs will take longer to copy into CONTIG.ISO, so it is best to defragment the E2B drive if possible before you boot to E2B. Tip: A quick way to make a large file of a specific size is to use the RMPrepUSB - Make ext2 FS button.
Tip: Some non-contiguous linux ISO files can be booted using E2B's isoboot feature - select the ISO in the menu, hold down the SHIFT key and press ENTER whilst keeping the SHIFT key held down. This should run isoboot. E2B v1.62+ is required.
When installing from an XP Install ISO, it reports in text-mode Stage 1 that it cannot copy the FiraDisk driver files - why?
For non-standard XP Install ISO files, I recommend you create an XP Install USB Flash drive using WinSetupFromUSB - then use the MPI Tool Kit to make a NTFS .imgPTN file from the USB Flash drive and add the .imgPTN file to your E2B USB drive. For more details, read my blog post here.
You are probably using a modified version of the ISO. It probably contains a \i386\winnt.sif file with the following line:
Usually this issue is caused by the OemPreinstall entry being set to Yes in the Unattend section of the Winnt.sif file, so you should change it to No - the example below will work almost automatically, note the line in bold red. Be sure to set a valid Product key. Alternatively you can delete or rename the \i386\winnt.sif file in the ISO and enter in the key and other answers manually.
E2B v1.62+ versions detects a winnt.sif file containing OemPreInstall=yes and will offer to modify the winnt.sif for you so that it will install correctly. if you load the XP ISO into memory, it will automatically remove the OemPreinstall=Yes line.
Note: ISO files which contain a \$OEM$ folder may not work correctly with E2B (e.g. Error 0x80070002 - cannot validate) if you change the OemPreinstall value to No.
The OemPreinstall option is set by default to No but if the ISO is using the $OEM$ Distribution Folders then it needs to be set to Yes, so that Setup regards this installation as a distribution and copies these files over to the system drive. This occurs at the end of Text-mode Setup. However, having OemPreinstall set to Yes will also prevent you from loading RAID/SATA drivers and FiraDisk/WinVBlock drivers using E2B DPMS or F6 during textmode setup. This means that the E2B installl of XP from an ISO file will not work correctly with .iso files that contain a $OEM$ folder. The only workaround for the problem is to directly integrate the firadisk and mass-storage drivers into the CD, as described here.
