agFM v1.75 released (bugfix for Windows ISOs not booting in Legacy mode)

I accidentally introduced a Legacy Windows ISO problem in agFM v1.73 and v1.74.

In an attempt to fix a grub2 bug involving the loopback command which caused a problem on some PCs, I changed the windows iso code to load some required uncompressed files instead of compressed .xz files. Unfortunately, although this worked for UEFI mode, it seems it does not work for Legacy mode (for some strange reason - must be a grub2 bug?).

I have therefore changed back the grub2 code to load the compressed .xz files if grubfm is booted in Legacy mode. 

i.e this code

loopback wimboot (${user})/boot/grubfm/wimbootxz;

loopback install (${user})/boot/grubfm/installxz;

works in UEFI mode but for some strange reason not in MBR\Legacy mode!

eBook 'Getting started with Ventoy' v1.04 now available

 I have made some small updates to my eBook 'Getting started with Ventoy'.

You can get the new version by using the original link in the confirmation email that was sent to you when you first purchased it.

If you haven't got it yet, it is available here (with 10% discount on total if you buy more than one).

E2B v2.11c Beta is now available (but needs some English strings translated)

The latest Beta of E2B is now available: v2.11c.

Some of the .mnu files for UEFI/agFM/Ventoy support in \_ISO\MAINMENU folder were 'hard-coded' to English. In the new Beta 2.11c I have now put the menu titles into each of the language files (however they are still in English):

E2B UEFI File Manager agFM v1.74c Beta.zip with new Ventoy partition image support available

It was previously possible to make partition images of Ventoy and then replace Partition 2 of the E2B USB drive with the Ventoy partition image, however in Ventoy v1.0.57 onwards, extra checks have been added into Ventoy and it now checks for Ventoy grub2 boot code in the MBR of the drive. This means that new versions will no longer work as partition images. :-(

However, I have modified the script and .cfg files so that it now also replaces the grub4dos boot code with the Ventoy grub2 boot code. The result is that we can now make Ventoy partition images again and boot to them and Ventoy still thinks the drive is an 'official' Ventoy USB stick.

Note that this exercise is only for someone who knows where their towel is and don't try it if you have not made a backup of your E2B drive just in case something goes wrong!

Instructions

New Beta version of E2B with bugfix and latest E2B+grub4efi Beta

 I found a bug in the latest release version of E2B v2.10 - file extension overrides no longer work.

e.g. a filename of Ubuntu_.isodef.iso should automatically use the .isodef extension, or  win10pe_.isope01.iso should use the extension of .isope01 but in the latest version it doesn't work.

The new Beta version of E2B with a bugfix for this is v2.11a.

The Beta download folder is here.

Note that the latest grub4dos releases are not used by E2B. Some new bugs and incompatibilities have been introduced and also the old grub4dos utilities such as wenv and fat and hotkey no longer work with the new grub4dos versions and you have to replace them with new compatible versions. So although the latest grub4dos versions have a few new features (e.g. allowing menu titles and menu help text to be in multiple colours), I still use a February 2020 version of grub4dos in E2B.

E2B for UEFI

I have also updated the E2B+grub4efi experimental version which uses the latest version of 'grub4dos for UEFI'. It is now version v2.10i. For instructions on how to use this grub4efi version see the previous blog article here.

Note that grub4efi (grub4dos for uefi) is still buggy. It crashes if you try to use the map command on iso files too often and it does not support wimboot so I have to use grub2\agFM to boot to WinPE and wim files! Because of this, I don't see grub4efi as being very useful so this Beta is for experimental use only and is just for the curious.
