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!
