E2B v1.B9k with grub4dos 'Error 25:' bugfix

There was a bug introduced into some recent grub4dos versions used in E2B v1.B7 and 1.B8.
A typical symptom is 'Error 25: Disk read error'.

To fix the error, it was necessary to make sure all ISO files are contiguous by running \MAKE_THIS_DRIVE_CONTIGUOUS.cmd.

E2B v1.B9k2 has the new grub4dos version (v1.B9k had the old version).

previous versions:
2019-08-09 OK (E2B v1.B5)
2019-09-09 OK (E2B v1.B6)
2019-10-28 FAIL (E2B v1.B7)
2019-12-30 FAIL (E2B v1.B8)
2020-01-28 FAIL (E2B v1.B8A)



Other changes:

  • The \_ISO\docs\Wincontig folder can now be copied to any drive volume and be placed in any folder. You can then make files contiguous on that volume by running one of the .cmd files.
  • Bugfix - set EXTOFF=1 did not suppress the file extension in the menus.

agFM v1.21 Beta now available

The developer a1ive has yet again done loads of brilliant work and managed to get the contiguous file test working for the partnew command. He has also added multiple language support to the main English version - just press F4 and select a different language or set the language in your user startup_menu.txt file.

F4 Settings Menu (auf Deutsch).

In your startup_menu.txt file, set the desired language:
#set language: en_US, ru_RU, fr_FR, tr_TR, ko_KR, ja_JP, zh_CN, de_DE, he_IL, vi_VN, es_EM, zh_TW
export lang=de_DE

I feel that the UEFI agFM system is getting very near to release status now, so please try it out for yourself.

Try the new version.

agFM v1.20 now available

The main change in this version is that a1ive has added an option to remove filename case sensitivity.

I don't know about you but I find the case-sensitivity of Linux\grub very annoying - especially when you have to verbally tell someone the name of a file and you have to say 'oh - and you have to type it with an uppercase F and a lowercase u'!

This change means we don't need to use the exact case for any letters used to specify the filenames in any of the .cfg or .grubfm menu files that we make.

There is now an extra option in the F4 Settings menu to enable case-sensitivity if you wish to have it on. You would only need to enable case-sensitivity when the same folder has two files with the same name but some of the letters were in a different case - which is quite unlikely!

agFM is looking quite nice now, however there is one major issue to overcome which I hope a1ive can crack. When using the partnew command to switch in partition images or ISO files, we should check to make sure that the file is contiguous. If it is not then it may fail to boot or it could even result in serious file corruption of the E2B drive! However the grub2 commands used to check if a file is contiguous (blocklist and stat -c) currently take over 1 minute to check a large 3GB file if the file is on an NTFS partition. If there are two files to switch in then it can take even longer. The partnew command currently does not check that the .imgPTN or .ISO file is contiguous.

E2B v1.B9j Beta available + grub4dos bug discovered

This version fixes the issue where Make_E2B_USB_Drive.cmd did not make a CONTIG.ISO file when requested.

It also now searches on Partition 3 for partition image files which have no file extension.

e.g.
Ptn1: \_ISO\WINDOWS\WIN10\Win10 x64.imgPTN23    (FAT32 boot files)
Ptn3: \_ISO\WINDOWS\WIN10\Win10 x64    (NTFS >4GB INSTALL.WIM)

The Win10 x64 file (which has no extension) can either be in the root of the volume or in \_ISO or in the same path as the .imgPTN file. The file name should not have any dot in it or else it will be treated as having an extension.

This means the .imgPTN23 file can be the FAT32 boot partition and the file with no extension can be the NTFS volume containing your large install.wim file. You can secure boot and install >4GB install.wim files in this way. Instructions are on the agFM E2B page here.


Grub4dos bug discovered!

ESET + persistent updates instructions now revised

The previous Eset blog article was tested (with much frustration) by 'Pusher' who could not get the Eset SysRescue app to auto-run.

It turns out that my instructions were wrong and the ext3 persistence file must be copied from a working Eset flash drive (as detailed in a previous blog).

I have revised the previous instructions now and provided a download for the persistence file to make it easier to set up.

Sorry for any frustration that this may have caused anyone!

Trouble finding WinPE ISOs?

Recently, it seems very hard to find WinPE ISOs such as Gandalfs PE,  Bob Omb's WinPEs, Medicat, DLC Boot, etc. and some websites (like theoven.org) seem go up and down faster than a tarts knickers!

Other sites just seem to be blocked (by Windows? AV? Browser?) and request a username and password but don't let you sign up first!

Google also seems to have a hard time returning meaningful results too.

After a few hours of looking for various bootable ISOs I eventually found:

https://www.fcportables.com/boot-iso/

They seem to have a good selection and the download is not too hard to get to!

P.S. I am not recommending this site and have no connection with it. Please ensure you take any necessary anti-malware precautions when downloading from it!
