Hi Steve. Great work.
By default, when I select any ISO payload on Menu, E2B shows as Help text under menu the Directoy location of ISO payload.
When I make a .txt file to display title of each ISO payload, then I cannot see these Directory locations how was by default.
Please. What "variable" must I adding to .txt files to show that location data to each ISO?

You can use $HOME$ and $NAME$

(but not for Windows Installer ISO .txt files)

Subject CSM is NOT UEFI!

Reply

Never have I seen/heard so much verbiage that appears intent to obfuscate the fact that Easy2Boot itself cannot boot in a UEFI environment; it can only boot under a 'standard' BIOS (whether actual or emulated as CSM).

Tell me I am wrong - nothing could please me more.

Better yet, show me how to create a Easy2Boot USB drive that itself boots under 'standard' UEFI (not CSM), preferably without mention (let alone half the discussion) of any virtual machine. Even better, present an approach that does not involve any Microsoft product other than FAT32

Date 12/02/2017

By SteveSi

Subject Re: CSM is NOT UEFI!

Reply

Hi
E2B supports UEFI-booting in two ways.
1. Use .imgPtN files
2. Use the grub2 menu system (MBR or UEFI-boot)
As you correctly point out, grub4dos cannot be booted in UEFI-mode. So with .imgPTN files, you need to switch-in the partition before you can UEFI-boot. It does mean that you can secure boot from a wide variety of UEFI OS's - something that no other multiboot USB solution can do!
There are videos about .imgPTN on YouTube and there is a page about the grub2 menu system (last in side menu tab).
grub2 menu systems are not generic, each menu has to be tailored to each individual payload. This means that those solutions need to be continuously updated/maintained.
If you want to GENERIC UEFI-multiboot for a variety of different payloads and want to prepare it under linux, then look elsewhere (and let me know if you find one)!

RMPrepUSB will tell you what type it is.
If it is Removable type then it is OK.
E2B only WARNS if any drive is over 128GB - it does not say that it will not work - it just says that Fixed disks will not work.
E2B (grub4dos) cannot distinguish between fixed and removable property - so it just looks at size and warns user if over 128GB because it is probably a HDD.

Subject Booting Windows ISOs

Reply

I am having problems booting Windows installation ISOs via Easy2Boot. I have got it set up fine booting to Acronis, Linux ISOs and various WinPE ISOs, but when I try to install Windows things generally go like this:

A) After choosing an ISO I get a menu of options, most of which I don't understand. I just want the ISO to behave in the normal fashion, so I choose the option that I guess is going to get closest to that.

B) 9 times out of 10, it doesn't work. e.g. I just installed W7 on a PC, that worked fine, but now I am trying to install W10 on the same PC and it's stuck at "Setup is starting". I have tried 2 different options.

Any advice?

Date 31/01/2017

Subject Re: Booting Windows ISOs

Reply

Any error messages at all from E2B? What is size of USB drive? What is type of E2B drive?
Delete the ISO. Then copy the ISO again to the \_ISO\WINDOWS\WIN10 folder.
Run \MAKE_THIS_DRIVE_CONTIGUOUS.cmd
Now use a Windows utility to get the CRC\MD5\SHA1 hash value of the file on the E2B drive and compare it with the same file that you downloaded onto the system hard disk (or with official published value). This will check the file for corruption. If not same you have bad USB drive.
Otherwise, it may be a hardware issue with Win10. If it was an E2B issue, I would expect some other sort of error. For Win10 you need to choose correct Product Key for the version you are installing - but you should get an error message from Windows Setup if it was wrong.

Thanks, it was a corrupt ISO.

That left me with another problem - booting via Easy2Boot does not behave like booting from a real disc. In this case, all the Easy2Boot options I tried either asked me for a Windows 10 key (which I don't have because the Windows 10 licence on this machine came via an upgrade from Windows 7) or left me with an installation that would not activate.

Booting from a real disc (actually an SD card with the ISO installed on it) installed & activated fine without entering a product key.

Is there any way I can make Easy2Boot Windows installs behave exactly like installs from real discs?

Subject Re: Re: Re: Booting Windows ISOs

The keys that are provided in E2B are installation keys. If you are installing Win 10 Pro (retail) simply pick the Win 10 Pro installation key.
Once you have booted to Desktop, you can enter the Win7 key and it should activate.
However, if you want it to be able to accept your Win7 key during Setup, use the MPI Tool Kit to convert the ISO to a .imgPTN file.
This will then behave like the DVD.
MPI will ask you about an EI.cfg file - if you have a retail ISO, say R and you will be able to install either Core or Pro (it will ask you to pick).
With .imgPTN (FAT32) you can also boot via UEFI too if you wish. See videos for more info and MPI pages on this site.

FASTLOAD is not the problem if you have not enabled it and it only caches the MAIN Menu, not the Linux menu.

Here's some surprising findings:

The problematic Kingston SE9 G2 USB 3.0 64G key works for:
- qemu
- my work machine Dell Precision T3610, all usb ports
- my older laptop Dell Vostro 3350, all usb ports
- my current laptop (where the problem originally occured) Dell Latitude E6230, only on the USB 2.0 port (USB 3.0 port do not boot). On the USB 2.0 port, it displays "Invalid Partition table!", then I press enter and it continue to boot the usb key.

Note that as previously stated, the USB 3.0 port did work once, then stopped working. Also that same USB 3.0 port was able to boot a smaller and supposely cheaper quality Kingston DataTraveler 101 G3 16 G.

I also destroyed the partition table on the 64G key, recreate from scratch, then format again, same result. This is using latest Easy2Boot_v1.86DPMS.zip, the fmt.sh script (Fat32).

I verified by Latitude e6230 is using Legacy BIOS and not UEFI. My ssd boot drive is using MBR partition anyways so it can not be using UEFI.

I am really stumped. Any other pointers as to why this weird problem happens?

I bought a bigger usb key so I can put my entire collection of Iso on it. I hope it is not the size of the key that is the problem because that will make me really sad.

The fmt.sh script does not add a small second partition. As explained on the website, when you use RMPrepUSB or the MAKE_E2B_USB_Drive.cmd Windows script, it makes a second small hidden partition on the USB drive. This is because some systems will try to boot a USB drive as a floppy disk if they only have one partition.
Can you add a small second PRIMARY partition to the USB drive or use the Windows script to make it?

Added a 2nd primary partition, still the same weird behavior.

Did you switch off the system and switch on again?
Did you check the BIOS settings. e.g. USB Settings?
Does it say USB HDD in the BIOS boot menu?
Is the first partition marked as Active (boot flag)?
Did you install grub4dos to both PBR and MBR?
Latest BIOS version is A16 25th Oct 2016 with improved USB support. Do you have this?

Yes

Yes, boot order is USB first.

Does it say USB HDD in the BIOS boot menu?
This is the interesting part, it doesn't say when the usb key is plugged into the usb 3.0 port. Looks like BIOS do not detect/see a usb hdd on usb 3.0 port ... but only for my new 64G usb key. The older 16G usb key was booting fine from that same usb 3.0 port.

Is the first partition marked as Active (boot flag)?
No.

Did you install grub4dos to both PBR and MBR?
I don't know, I just run the fmt.sh script.

Latest BIOS version is A16 25th Oct 2016 with improved USB support. Do you have this?
I only have A15.

I also tried to format the usb key using Windows instead of linux. This is the latest fdisk output after Windows format:

sudo fdisk -l /dev/sdb
[sudo] password for lvu:
Disk /dev/sdb: 57.8 GiB, 62087233536 bytes, 121264128 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xfc5ed0c2

Device Boot Start End Sectors Size Id Type
/dev/sdb1 * 63 121242491 121242429 57.8G c W95 FAT32 (LBA)
/dev/sdb2 121242492 121242554 63 31.5K 21 unknown

Still the same behavior (usb 3.0 port do not boot) with formatting using Windows. However at least usb 2.0 port stop staying "invalid partition table!".

I guess a new BIOS might be the fix. At least now the usb 2.0 port boots properly so I have a fall back. I'll reply my findings if I feel brave enough to update the BIOS. I got burned once in the past updating BIOS.

Thanks for all the help. Looks like formatting on Windows does a more complete job than Linux. Is it because Linux is lacking any functionality or you just didn't get around to have feature parity between Windows and Linux?

I am still puzzled as to why my older 16G usb drive was working fine on that same usb 3.0 port although it was formatted on Linux.

I think means that the partition is active. So one difference is that the first partition was not active until you used Windows to prepare the USB stick.
The fmt.sh script only formats an existing partition it does not create partitions.
Did you enable both options in the BIOS under System Setup - USB Configuration - Enable Boot Support and Enable External USB Port?

P.S. I have improved the linux fmt.sh script in E2B v1.87b so that it makes the partition active and installs grub4dos to the PBR.
The only thing it does not do is make a 2nd small partition on the USB drive. You should do this yourself or it may not boot on some systems.

Subject E2B Multi-Boot

Reply

Dear Stevesi,
first of all thank you for the software package development and that for free!
I've been trying to make a Multiboot USB Stick/HDD usable for both UEFI and Legacy Mode Bioses and I've already read several tutorials on E2B website and have also seen several videos from other resources. But still haven't been able to make such a drive, which would work on both kind of Bios types (MBR/UEFI). The best results have been either working on some MBRs OR on some UEFIs, not both at the same time.
Therefor my first question is that, if you could recommend one main method/tutorial to focus on; because as I mentioned there are several Versions suggesting different methods, like using RMPrepUSB (and that with variety of options like choosing between ntfs or fat32, Boot as HDD as checked or not etc.) or using the scripts like MAKE_E2B_USB_DRIVE .cmd
My other question is that, if you by any chance know some tool to convert usb "fixed" drives into "removable" disks? Most of my USB drives are detected as "fixed" drives. I assume that, first of all they have to be "removable" drives for being able to make them bootable using E2B.

E2B will work on Removable drives or Fixed Disk type.
The website explains the difference.
Not all payloads (ISOs) support UEFI booting.
Look at the 'List of tested payloads' page to see the best way to add each payload file.

That is tricky!
When you boot from USB, hd0 will be the USB drive.
hd1 will be the first internal hard disk.
So if you want to boot from the internal disk try
iftitle [ls (hd1,0)/ntlrd] Boot from NTLDR

or maybe

iftitle [ls (hd1,0)/ntldr || ls (hd1,1)/ntldr] Boot from NTLDR

For interest
# Ignore boot device and boot to Windows XP, Vista, 7 or 8 from the internal hard disk
# This works by mapping the boot device (bd) which may have bootmgr or ntldr on it, to a virtual memory drive so that files on it are not found by the find command
title Boot to Windows from an internal hard disk
map --mem (md)+8 (bd)
map --hook
find --set-root --ignore-floppies --ignore-cd /bootmgr || find --set-root --ignore-floppies --ignore-cd /ntldr
map (bd) (bd)
map --rehook
chainloader /bootmgr || chainloader /ntldr

Subject Unable to defrag NTFS USB drive on Linux

Reply

Hi,

I got this error on Ubuntu 16.04:

[[email protected]:12 12:47:29 linux_utils]$ sudo ./udefrag -om /dev/sdc1
[sudo] password for lvu:
sudo: unable to execute ./udefrag: No such file or directory
[[email protected]:12 12:53:38 linux_utils]$

USB drive was created using Easy2Boot_v1.86DPMS.zip.

I used 'sudo bash ./fmt_ntfs.sh' to create the drive initially.

Then I copy over some .iso.

The udefrag binary is a 32-bit program.
If you have Ubuntu 64-bit, you may need to add 32-bit support. See the linux page on this site.

udefrag came from the tools.zip file at
http://jp-andre.pagesperso-orange.fr/advanced-ntfs-3g.html#download
If anyone would like to supply me with a 64-bit version of udefrag (find it or compile it), I will include it in E2B.

Yes udefrag file exist. Yes I chmod a+x it.

I will try to add additional 32-bits libraries to my 64-bits machine to see if I can run udefrag.

Thanks.

Confirmed able to defrag NTFS on Ubuntu 16.04 by following intructions on Linux page:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
(change to _ISO/docs/linux_utils folder)
sudo chmod 777 *
sudo udefrag -om /dev/sdX1 (where sdX1 is your NTFS USB partition)

Thanks.
