Add ESET antivirus ISO with persistent updates to E2B (revised!)

For a different method using a .imgPTN file, please see the  next post!
______________________________________________________________________________

E2B can boot the ESET System Rescue ISO easily, but each time you have to download the latest updates which can take a while.

The current ESET disk eset-sysrescue.1.0.9.0.enu.iso does not support UEFI booting, but here is how to MBR-boot with persistence for updates, direct from the .iso file:

ESET ISO + PERSISTENCE

You will need a working, ESET SysRescue flash drive.

1. Copy the eset-sysrescue.1.0.9.0.enu.iso file to the \_ISO\ANTIVIRUS\MNU folder (or any standard menu folder at the 3rd level down - e.g. \_ISO\MAINMENU\FRED)

2.  Run RMPrepUSB and select the ESET flash drive and run Drive-File - Filename= C:\eset - Start=P3 - Length=P3 - File position = 0. This makes an image of the entire 200MB P3 partition which contains the ext3 filesystem and any new update files.

Note: Recent versions (2019/2020) use P2 for the persistent partition (488MB approx). The persistent partition must be in the same position as used by ESET, so this means that the persistent partition needs to be placed in P2 on the E2B USB drive. This cannot be done on E2B drives as it would destroy Partition 2!

3. Make a .mnu file as below using Notepad, and copy it to the same folder as the .iso file.

NEW VERSION! Note lines in red!

\_ISO\ANTIVIRUS\eset-sysrescue.1.0.9.0.enu.mnu

# Place this .mnu file and the ISO in either \_ISO\MainMenu\MNU or \_ISO\ANTIVIRUS\MNU
# This menu will work even on an NTFS USB boot drive
# IMPORTANT: you MUST run WinContig (Ctrl+F2) before booting E2B.

You should now have on your E2B USB drive:
\_ISO\ANTIVIRUS\MNU\eset-sysrescue.1.0.9.0.enu.iso
\_ISO\ANTIVIRUS\MNU\eset.mnu    (any name will do!)
\eset

4. Boot to E2B - Antivirus Menu and select the  new Eset PERSISTENT menu

5. At the ESET desktop, first accept the Licence Agreement by selecting the two options and clicking 'I accept'

Now, any updates you make will be persistent.

The .mnu file will be added to the \_ISO\docs\Sample mnu Files\Linux folder in the next version of E2B.
