I just found this buried in the manual. It seems you can use the RAID firmware!

Creating a JBOD Configuration
The BIOS RAID utility does not report non-RAID drives to the system BIOS. If a non-RAID boot drive or data drive is desired, create a JBOD so the BIOS RAID utility will report the drive to the system BIOS.
1. Select 'Create RAID set' from the Main Menu section of the RAID Configuration Utility screen.
2. Select 'JBOD' and press Enter.
3. Select 'JBOD drive' from the Physical Drive list and press Enter.
4. Select the size of the JBOD drive with the ↑ and ↓ keys and press Enter.
5. When the 'Are You Sure?' confirmation prompt appears, respond 'Y' to complete the JBOD configuration.

The hard disk should now be listed in the BIOS menu as a 'JBOD' device.
Obvious, isn't it! To add a non-RAID single disk, you use the Create RAID set option!!!

I have given up on this for now. I have been at this for 12 hours. I can not get the second stage of XP to start. In order to get the first stage to successfully run. I would wait until the XP files were copied to RAM disk. then before the XP install started, pull the USB drive to prevent XP from overwriting the boot record.
the first stage install would run successfully and reboot. After the 2nd stage completed its copy it was suppose to boot off the hard disk, and this would not happen. I could not get the second stage of XP to work properly. I am going to use old school, stream line a set of drivers and do it this way. I will continue to monitor this thread for possible solutions.

Passcape Reset Password is based on WinPE. It may not have the drivers required for your (modern?) PC. Try using a USB 2 port for the kbd and mouse. Since it is a commercial program, contact Passcape. The latest trial version seems to have drivers which were added on Jan 2019 - so it seems up to date and should work. Is your ISO too old?
Also, try converting the ISO to a FAT32 .imgPTN file and see if UEFI-booting works?

I've been using Grub4dos for a long time and I've set up my menu with all the things i use the most at the top of the screen (HDSentinel for dos and then a space) and then after the space i have Cloning Software clumped together like Acronis,Paragon etc..These arent in sub menu's, they are launched directly from the main menu.
Then I have another space and after that i have partitioning tools, once again Acronis,Paragon etc.
Then another space and after that portable OS's , Hirens Windows 7,Gandalfs Windows 8 & 10 etc.
Then another space and finally under that i have submenus of the things i don't use as often.
Its just there is sooooo much information I'm having trouble coming to grips if i can move out the default menu's completely, Insert my top options and add a line in between the different genres of programs.
I took some quick pictures of what I'm trying to achieve but there's nowhere to post them unfortunately.
Is there anywhere i can download peoples e2b config files or even whole iso images of usb sticks that i can go through and see how they've done it...Thats originally how i learnt on grub4dos...pulling apart somebody else's work, making changes and seeing what it did, seeing what changed.

Hi
The first entry you have is Hard Disk Sentinel for DOS. So copy the ISO to the \_ISO\MAINMENU and boot to E2B and try it. It will appear in the Main Menu is 'hdsdos' but you can change the file name to 'Hard Disk Sentinel (DOS).iso if you like. If you want it in the Utilities menu, then just copy the ISO to \_ISO\UTILITIES.
If you want it to be listed as the first entry, name it aaa_hdsdos.iso. Entries are listed alphabetically by file name.
Now to change the entry text and also add the lines of help text under the menu when you select it, create a aaa_hdsdos.txt file using \_ISO\Txt_Maker.exe.
The next item you have is a blank line, so copy "\_ISO\docs\Sample mnu files\E2B Menus\A_BlankMenuEntry.mnu"
to \_ISO\MAINMENU folder and rename it as aab_blank.mnu.
The next item you have is Acronis True Image 2018. So copy the .ISO file to \_ISO\MAINMENU and name it aba_Acronis2018.iso. Then make a aba_Acronis2018.txt file for it.
Rinse and repeat...
For some of the other items, e.g. Antivirus, backup, Windows Install, just copy the ISOs to the correct E2B menu folders.

The other alternative is to simply use your current menu.lst file. Copy your menu to \_ISO\MAINMENU and name it 'Batfink Menu.mnu'. Edit it to remove the initial grub4dos lines so it starts with 'title xxxx' and all the following entries. Copy your ISOs to the correct folders on the E2B drive as expected by your menu.

You can always start a chat session with me if you have any problems. There should be a chat icon pop-up on this page.

Is the sorting Alphanumeric, When i first started with just HDsentinel and the cloning software i could have sworn they were in the correct order.
Then I added a space and added partitioning software, Removed the backdrop,set it to 1024..I know it looks like a dogs breakfast, I was going to ask and read a bit more about removing help menu's and highlighting menu items etc..eventually.
However, This is driving me bonkers ..as you can see from the explorer picture all my files are in perfect alphanumeric order and yet in the second picture you can actually see them detecting in the wrong order as the USB stick boots, and finally in the last picture you can see them in the wrong order (or the same order they detected in)

Whoops! You have found a bug! Though I did tell you to use aaa not 000 ;-)
It is because grub4dos is treating 002f as a number and is discarding the non-numbers, so 002a is smaller than 002g (g=GB so 002g=2GB whereas 003d = 3 and 002f=2). grub4dos treats k,m,g and t as multipliers and so the list is not sorted correctly. You can use a non-number as the first character and it should work correctly - e.g. @002f-
or download the latest E2B v1.A9j Beta from the Alternate Download Areas on GDrive or OneDrive.

if you try the latest version, please let me know if it works or not.

You're hurting my brain ;)
Your beta worked perfectly, I upgraded it directly over the USB stick.
I'm actually pretty bland when it comes to this stuff, I don't need a backdrop at all, or a logo..just a surrounding box is good enough...It's a tool, not a Picasso :)
I don't even need a help menu, Its for me, I know what everything does since I made it, The more i can fit on the screen the better.
That being said, I do like a menu thats easy to see, Easy to tell whats selected so i have a couple of questions.
1. In the Imgur pictures i posted you'll notice the text is white unless selected and then a large white selection over it highlites it and makes the text under it black..nice and easy to see...Can that be done ?
2. Also the RETURN TO PREVIOUS MENU (F8), is that location set in stone, can it be moved to the top of the sub menu's and be the default item selected and set apart with a space so if you're looking for something and went to the wrong menu you can just press enter to go back.
3.Is there a way to actually completely remove the help ...I did move it down totally off the screen but for the built in items (MENU REFRESH) like shown in the picture it still shows up in the default place.
4.Can i move the wwww.easy2boot.com to maybe the top of the main menu where it shows the version number.
Hahaha, So many questions, so little time..I'm appreciative of all the help you've given me so far.

1. As in the Sample_MyE2B.cfg and on the http://www.easy2boot.com/configuring-e2b/ page,
the selection text can be highlighted by defining a highlight colour - e.g. color highlight=0xFFFFFF00000000
2. Any menu can be removed using one of the NOFxxx variables in your MyE2B.cfg file. Any new menu can be added by adding in a .mnu file (see v1.A9k Sample mnu Files\E2B Menus for example .mnu files). A menu space can be added as already explained by adding a .mnu file. http://www.easy2boot.com/configuring-e2b/mainmenuonly/
3. Help can be removed using set NOF1=1 in your MyE2B.cfg file - http://www.easy2boot.com/configuring-e2b/f1-help-menu/
4. The FOOTER help text can be removed by setting its position to just after the last line of the menu - or moved - using HBTM. The Main Menu heading is determined by the HEADING variable. As already explained, the E2B_Editor.exe GUI will help you and it already has an Options list for suppressing F1 and F8, etc.
You may find it useful to define Global Hotkeys - http://www.easy2boot.com/configuring-e2b/global-hotkeys/
and look at the Sample_MyE2B.cfg file which contains a load of example settings. Use the SITE MAP!
P.S. grub4dos does not UEFI-boot. You will need to use grub (grub2) for a UEFI menu system or the new syslinux for UEFI.

boot.wim files (the WinPE that is initially booted to from an ISO or MDT, etc. when deploying an image) are typically 300-800MB in size. They typically run Setup.exe which is used to deploy a second much larger install.wim file to a target system.
The large install.wim is not usually bootable and contains a copy of the OS files that you want to install onto the target device.
All bootable .wim files are always loaded into memory as the X: drive. You cannot boot the install.wim type of file with E2B or MDT or Microsoft bootmgr+BCD because it is not intended to be bootable.

Subject How to restore E2B partition after switching to .imgPTN file

Reply

So far the only thing I didn't accomplish, using E2B is, to switch back to the regular Legacy Boot menu after booting a payload via an imgPTN file. (I know, this is not the right place for support, but as I hope I am only to stupid / blind to find the hint and you can help me with one link I didnt find so far, I ask it here:
I boot a payload via ImgPTN, but not in UEFI but in CSM Mode.
1. I boot in the regular E2B menu, chose the .imgPTN payload and the MBR gets overwritten (-> the partitions switched)
2. I boot the payload (also in CSM Mode) and use it, so far it works like you describe in the corresponding instruction.
3. How do I flip the partitions back now (to get back to the regular E2B menu) without the need to boot a windows and use the .exe ? In your article about the use of imgPTN files you write, that after I booted the stick in UEFI-Mode to boot the payload I will get an simple menu with the option to switch back the partitions if I boot the stick in legacy / csm mode again. This doesn't work for me since I boot the payload again immediately when I boot the stick in csm / legacy mode. That is logically because the Bios / UEFI only sees this one partition after the partition swap. Does this mean, its impossible to switch back the partition table without a working windows-pc or am I just to stupid to understand, how it works ?

However, I can totally live with this limitation since I mostly use payloads that doesn't need the imgPTN trick to work, I just wondered if I've missed the trick of switching back.

If you UEFI-boot to Windows\WinPE then you can use one of the utilities in the \e2b folder to restore the E2B partition.
If you UEFI-boot to linux, then you can use the \e2b\Restore_E2B.sh bash script to restore the E2B partition (it will be in MPI v0.090 and later versions).
Otherwise you must find some other way to MBR-boot or boot to a linux or Windows\WinPE system in order to switch back in the E2B partition.
If you want to try a variety of linux payloads from a single UEFI menu, try the E2B grub2 menu system - see Site Index for the page (but it has it's own set of drawbacks).

In fact the only tool I would want to use on daily basis would be rescatux (by the creator[s]) of the SuperGrubDisk. Since that is based on a linux live system, the bash file should work. I will try that.
I've read the page about using grub2 instead of grub4dos, but because of the drawbacks (and because of the fact that I wouldnt consider myself as an "expert" in terms of booting) I didnt try it so far.
Thank you for the fast response.
Also I tried to boot the switch-back-menu again on a much older laptop - and it works. It seems to be a problem with my current device (Acer Travelmate x349). Do you have any other advice considering the UEFI-Settings except Secure-Boot=Off, Fastboot=Off, Legacy-Boot/CSM=On that might help me to use the switch-back-menu on my laptop ?

You have found the exact reason why E2B uses the .imgPTN scheme! Some BIOSes will ONLY UEFI boot from a UEFI-enabled USB drive even though you have enabled CSM mode. Many BIOSes have this bug. It means such solutions as SARDU or WinSetupFromUSB or YUMI will only be able to UEFI-boot on your system and it will never boot to the MBR menu so you cannot run any MBR payloads on those systems (unless you delete\rename the \EFI folder).

Either you have not set the BIOS options correctly OR your systems have this BIOS bug.
To check, select one of the .imgPTN images which show the problem and confirm that it will not boot to the CSM MBR menu. Then rename the \EFI folder to \EFIxx and try again. If it now boots to the CSM menu then your BIOS has a bug or it is set to boot from UEFI first. If it still does not boot to the CSM menu then you have not set up the BIOS settings correctly.
Always use the F8/F12 or whatever function key to get the BIOS Boot Selection Menu pop-up - do NOT set the boot order in the BIOS Settings menu to boot from USB first.

I checked my BIOS settings again. My Bios has only 2 options (concerning boot style): Legacy (only) and UEFI (only). So I dont have any option on how to boot the stick in the boot menu (like UEFI USB Stick: SanDisk... / USB Stick: SanDisk...) And since my local OS is MBR-installed, Legacy (only) is the choosen setting.
If I switch to an imgPTN Partition, the first time I boot I get the CSM menu. After I have booted the imgPTN-Payload once (Legacy-Mode, ofc.), my Notebook boots the payload immediately. This doesn't happen if I rename or delete the EFI folder. If I do that, it always boots to the CSM menu. I guess that means: buggy bios confirmed.
So I can't use the imgPTN-trick for uefi-booting (and switching back easily) with my notebook, but that's not realy a problem since I can totally live with Legacy-only booting. The only payload I wanna use on a daily basis that isn't bootable as a simple ISO is also fully functional when booted in Legacy-mode, so I will just delete its EFI-folder and use it this way.

Thanks again for the really fast and qualified help.

I still have one question: You wrote that I shouldn't set USB boot as the default option, but use the boot-menu-hotkey instead. Is there any technical difference between this two options ? If yes, what exactly ?

So what options do you actually see in the BIOS Boot selection pop-up menu? Does the BIOS Settings menu system show anything in 'Boot devices' or anything under + Hard disk?
You should not set the USB device as the first boot device in the BIOS settings because many BIOSes have a bug and they can tell an OS that the USB is the 'boot device' of your system. The result is if you then install an OS to your internal hard disk (XP, linux, etc.) you may find that the boot code and files have been installed onto your USB drive because that is the system 'boot device'.
Now the boot code on the USB drive is trashed and you can only boot to the internal hard disk if you first boot to your USB drive! This can often happen when using a USB HDD to install an OS from.
This issue can still happen when booting from the pop-up menu too, but E2B tries to fix it by swapping over the BIOS hd0 (USB drive) with hd1 (first internal HDD).

Okay, possibly I was describing it a little bit misunderstandable.
If I choose the way to boot in the BIOS / UEFI, I have only two options:
1. Legacy
2. UEFI
https://ibb.co/wdnPgyd
(Screenshot of my BIOS settings)
I know about other PCs (at my workplace, for example) which have a third option, like "UEFI and Legacy" (or with a similar name). Take the following BIOS-Screenshot for example (not my BIOS):
https://browse.startpage.com/do/show_picture.pl?l=english&rais=1&oiu=https%3A%2F%2Fi1.wp.com%2Fneosmart.net%2Fwiki%2Fwp-content%2Fuploads%2Fsites%2F5%2F2014%2F05%2FASUS-Boot-Device-Control.jpg%3Fssl%3D1&sp=93d3a0226b9295113b636263aaf675d2&rl=to&t=default

At that place I can only choose between UEFI or Legacy. At the PCs with the "both" option, I can choose at the boot menu wether I want to boot the device in UEFI or in Legacy mode, it looks like at this screenshot:
https://browse.startpage.com/do/show_picture.pl?l=english&rais=1&oiu=https%3A%2F%2Fi.ytimg.com%2Fvi%2FMHOP3VY4qZM%2Fmaxresdefault.jpg&sp=046dea4b255f12c3c9fb7bd8eba93bee&rl=to&t=default

And Since I can not choose the "both" option, I have no choise in the pop-up-boot-menu.
https://ibb.co/9b59NC0
<- My boot menu in legacy-mode) Thats all I wanted to clarify with my last post.

OK - if the BIOS allows it, you can try setting Secure Boot = enabled + Legacy boot. Then if the EFI boot files are not signed (secure) it may boot in Legacy mode. Some payloads may have signed EFI boot files however, in which case this trick won't work!

Hello again. I've set up another E2B stick. No background image issues this time!

But what is giving me a hard time is the ISO contiguous thing. For testing and demonstrations I made a 16GB Lexar USB3 stick with several flavors of Linux, like Fedora, Xubuntu, Manjaro etc.
After I loaded the ISOs I ran the make contiguous file and got an error there was not enough free space to make several files discontiguous. At this point there was about 2GB free. I started deleting some ISOs but the error would persist.

Finally, I removed all but one ISO, then could make that contiguous. Then I added ISOs one by one, each time running the make contiguous process.

I have about 5GB left and thinking about what would fit the idea of the stick I downloaded openSuse first to a harddisk. This image is 3.9GB large and I fear it can not be made contiguous if I copy it to the stick, and I would have wasted 4GB of the lifetime of the stick.

I do not exactly understand the purpose of the making contiguous process. I learned, fragmentation is no issue on flash memory, and even to be avoided.

When I write a single ISO to a single stick, there is never a problem with dis-contiguousness.

Subject Re: ISO contiguous issues

The file is required to be contiguous because E2B uses it as a partition and actually writes the start address of the file to the USB stick's partition table. Linux will then see the ISO as a partition and so can easily access the files inside the ISO. Partitions cannot be fragmented - they start at sector X and finish at sector Y in one contiguous block. So the ISO must be contiguous.
See http://www.easy2boot.com/not-contiguous-error/ for more info.
You need to realise that WinContig needs a contiguous block of free space in order to move the ISO and make it contiguous. I use Defraggler to consolidate the free space on the drive if the free space starts to get fragmented.
P.S. As I say on this site, 16GB is really the minimum size for a multiboot drive - because you need at least 4GB of consolidated free space to make a 4GB file contiguous. So Use the Action - Advanced - Defrag Freespace option in Defraggler and then copy on your last file.
P.S. NEVER download files DIRECTLY to your USB drive from your browser - it usually makes the file fragmented, even if there was enough contiguous free space on the USB drive, because it opens up several 'streams' when downloading the file.

After defraggling free space I copied the openSuse ISO and booted the E2B stick. A message appeared that Suse was discontiguous. I tried it anyway. I had to walk away for a minute and when I returned an installer had started: the Suse ISO wasn't a liveCD as I had intended! I'll remove it from the stick and find something else.

Subject Remastered Lubuntu doesn't boot

Reply

Hello, and thanks for this great tool!

What I want to do is this: add three or four Linux ISOs and make an Easy2Boot USB drive, make an ISO of the whole thing using RMPrepUsb, and then burn it to DVD. I have added two regular downloaded-from-the-website *buntu ISOs, and a Remastered version of Lubuntu (made using Pinguy Builder) in which I have added LibreOffice. This Remastered Lubuntu ISO alone boots in VirtualBox and directly on the computer, but when I add it to E2B and make an ISO of the E2B USB (to burn to DVD) and try to boot the Remastered Lubuntu by testing it in VirtualBox, I get a Kernel Panic.

E2B first tries to ISOBOOT the Remastered Lubuntu using ISO Cheat Codes, fails saying "Error: No initrd file found!", asks to "Press a key to boot..." to which I press the down arrow, a whole lot of text goes by as it tries to boot and then finally stops with the message: "---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0)". This same Remastered Lubuntu boots otherwise, only not in E2B.

Please help. I'm a noob in such matters.

Hi
So your only problem is the remastered ISO - the other two ISOs work fine?
You can test ISOBOOT from an E2B drive by holding down the SHIFT key before you press ENTER to run the ISO from the menu.
It is probably easier to start a Chat session with me on the website if the ISOBOOT web page does not help you.
http://www.easy2boot.com/faq-/isoboot/
If the ISO contains a casper-rw file, you will probably need to extract it to the root of the E2B USB drive.
If the initrd file cannot be found, then ISOBOOT is probably looking for the wrong file. Look at the isolinux.cfg or grub.cfg file inside your remastered ISO file to see what cheat code parameters it is using. Then make a new ISOBOOT.g4b file as described on the isoboot web page above. If the iso is using initrd.gz then you will need to add the 'try' lines into the :.isoubu code section.

Subject Re: Re: Remastered Lubuntu doesn't boot

I have been looking at an ISO built with PinguyBuilder and it does not seem to support any cheat code parameter to specify the name of the ISO file. This means that the only way to boot it as you want to do from an E2B DVD is to extract the contents of the ISO to root of the E2B drive. If it works, you could then remove those folders from the remastered ISO.
However, if you are booting other ubuntu-based ISOs, they may find the \casper folder on the root of the DVD instead of the \casper folder inside the mounted ubuntu ISO, and so they would all boot to your remastered files instead of the files inside the ISO.
I suggest making a special .mnu file, extracting all the files from the remastered ISO (so the .iso file is not needed):

title Start PinguyOS 18.04.1 Full LTS
kernel /casper/vmlinuz file=/preseed/custom.seed boot=casper quiet splash --
initrd /casper/initrd.gz
boot

This works, but if the \casper folder is renamed and the menu adjusted, it no longer boots and so the other ubuntu ISOs may get 'confused' still! See https://forums.linuxmint.com/viewtopic.php?t=35567 for how to modify it to boot from a different folder.

Sorry to bug you again, and maybe I am just typing what I typed earlier, but the problem I face is that the Remastered ISO only boots if the media is not write-protected. If I add the Remastered Lubuntu to a USB drive, reboot, and try to boot the Remastered Lubuntu normally, the regular way Easy2Boot boots it, it works fine. If however, I press the Shift key when selecting the ISO, it is not able to boot it.

If I try to boot it with the Shift key, first E2B asks whether to change the extension, then gives a screen with a huge list of options one of which has to be typed, and if I select the first option to just boot it, a lot of text goes by and finally it ends in kernel panic - "Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0)". But if at the E2B options screen where it asks how to boot the ISO, I select the option to load the entire ISO to RAM, then it loads the ISO to RAM and boots fine.

The problem I think is because of the media being write-protected. Is there any simple workaround for this?

If it works when you load the ISO into memory, then simply change the file extension to the one that works (e.g. .isomem).

But I already told you how to get it to work.
1. Extract all the files from the ISO onto the root of the E2B USB drive.
2. Add a .mnu file (as detailed earlier) to the \_ISO\MAINMENU folder.

Or just convert the ISO to a FAT32 .imgPTN file.

I would now like to create subfolders in this folder, such as "Ubuntu" or Debian. "This is how it should be visible in the menu, first as" Linux "and then follow the subfolders, but always with the" SUB_MENU_MAKER " only menu items in the main menu.
Can you tell me how I have to implement that, because I seem to be really stupid for it.

All menu folders must be directly under \_ISO.
To do what you want, just make a new folder called \_ISO\LINUX_Ubuntu and drag-and-drop this folder onto the Sub_Menu_Maker.cmd file. This will make a .mnu file in \_ISO\MAINMENU folder.
Then simply move the new .mnu file to \_ISO\LINUX folder. see

You cannot UEFI-boot to the E2B menu system.

If you want to UEFI-boot from the E2B USB drive, you must make a UEFI-compatible .imgPTN file using the MPI Tool Kit and then select the .imgPTN file from the E2B menu system (MBR-boot) or use \_ISO\SWITCH_E2B.exe to select the .imgPTN file.
Once the .imgPTN file has been 'switched in', you can then UEFI-boot or MBR-boot from the E2B drive.

Subject Re: Re: Re: Booting on GPT systems

You can MBR or UEFI boot from the same .imgPTN file - the ISO is not required if you use .imgPTN files.

The problem with other multiboot solutions is that some systems (Fujitsu LifeBook, Samsung, Acer and probably others too) refuse to MBR boot if an EFI boot file is present on a FAT partition. This means, that on these systems, they will not boot via MBR to MBR payloads such as Hirens, many linux OS's, DOS, Mini XP, etc. because they will *always* UEFI boot instead.
UEFI requires a FAT partition to be on the drive and many other products just use a FAT32 USB drive which limits the file size to 4GB per file.
You can try the E2B grub2 menu system, or other products such as YUMI UEFI Beta version, SARDU, WinSetupFromUSB (for Windows UEFI) or multisystem. http://www.easy2boot.com/uefi-grub2-ptn2/
I am afraid there is no good universal solution because of these 'buggy' BIOSes.
That is why E2B uses the .imgPTN scheme - so that you can boot on 99% of all systems including those with this annoying bug.
Also, the E2B .imgPTN scheme means you can Secure Boot and boot from a wide variety of payloads (linux, Windows, KonBoot, memtest, etc.) all from the one USB drive.

The warning message just warns you that there is no internal hard disk in the system. I do not recommend suppressing messages until you become experienced in E2B - the messages help you to get it to work properly!
If the system you use to boot E2B from has a hard disk, you won't see it.
The spinning logo animation is determined by the MyE2B.cfg file - see the set ANIMATE line?

It doesn't work, quickly (less than one second) It opens (F3 in RMPREPUSB) the RMPREPUSB's folder only and there's no message in RMPREPUSB's gui (only the "Error: etc." message, in red).
BUT, I FOUND THE CULPRIT: RMPREPUSB doesn't like its folder path (currently is "c:\(inLine\(LOW_LEVEL-OS_DEPLOYMENT\RMPrepUSB\").
I put It in c:\RMPrepUSB\ and all works fine!!
Sorry Steve :-(
Thanks

Using () parentheses in paths and filenames is a bad idea! Also using other odd characters like & and ! and | is a bad idea too!

Hi Steve.

I think I've found a critical bug in latest VBox 5.2.8. It causes a *host* computer BSOD when booting a VM using a physical E2B drive attached to host computer using the raw VMDK/Virtual Machine USB Boot tool trick.

Used E2B is updated to latest v1.98 and it boots the host physical computer as well as the same VM (if previous VBox versions up to 5.2.6 are used) without issuess.

I've narrowed the problem down to triggers being 2 lines (if commented out with # then no BSOD) in \_ISO\e2b\grub\menu.lst:

line 548
dd if=(md)0x3000+0xA0 of=(md)0xa000+0xA0 > nul

and line 575
cat --locate="\ntimeout " --replace=\n# (md)0xa000+0xA0

Both lines try to access memory at 0xA000 and seem related to the FASTLOAD feature. Other 3 lines access memory at that offset previously (443, 444 and 451) but I've not tested their impact because they are not executed if FASTLOAD is not enabled by user (I don't use it). However lines 548 and 575 are unconditionally executed.

This is clearly a bug in latest VBox (current and previous E2B works like a charm on real hardware and previous VBox versions), but I would like to get bug confirmation from you if possible since opening a ticket at VBox bug tracker is going to requiere some cumbersome account creation.

Thanks in advance.

Hi
Well done for tracking down the lines!
I noticed the issue too and have reported the problem on the VBox forum already.

P.S. 0xA000 is nothing to do with fastload, it is just where the Main Menu is stored by E2B (address 20MB) for quick reloading of the Main menu.

From MS debugging tools for Windows documentation:

https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0xd1--driver-irql-not-less-or-equal

I can generate a BSOD minidump + VBox logs as requested, but I have a suggestion instead: maybe you could create a small "BSOD trigger demo" menu.lst file for VBox devs to easily reproduce it, something that stops just before any of the trigger commands and waits for a keypress to execute. I guess they could install grub4dos to the VDI in a test VM + \grldr + \menu.lst. You can better guide them here: setup a shared folder with grub4dos installer + grldr + menu.lst, then boot VM i.e. to WinPE using a Win install iso, press SHIFT+F10 for cmd, and install and copy files to VDI root. Finally boot the VDI.

Hope the above makes sense.

I tried putting pauses in menu.lst code to find the point where it BSOD's and the two lines you indicated worked fine.
I found the cause was the map command (see link to forum for details). I can repro without using VMUB or .vmdk file or E2B.

Easy and to the point setup for checking the bug by devs.

However note: on my host computer I can bypass the BSOD by commenting out lines 548 (dd) and 575 (cat). Uncomment any of them (tested uncommenting one keeping the other commented) and I get the BSOD. That means line 504 (map, the ones causing BSOD for you) gets executed w/o BSOD.

My host is Win 7 x64, I think yours is 10 x64. Also, I'm assigning 4 GB RAM to my VM.

And maybe important: PAE/NX is enable as well in my VM.

Ok Steve, nothing changed in my setup, but some minutes ago I got a BSOD even with lines 548 (dd) and 575 (cat) commented out, so they are not the only triggers.

I've uncommented them (so both execute) and just commented out line 504 (map) and NO BSOD. Never touched that line in my previous tests (always executed). So it seems to be a trigger as well. I'll keep this mnu.lst (only skipping line 504) for further tests.
