Perhaps this one:
Booting an ISO off the disk is a neat parlor trick, but less useful than a proper Ventoy stick for ISO testing. With Ventoy you can just throw ten ISOs on there if you want to, and get to work without having to redo the setup in between.
What would be really neat would be to have a Ventoy option built in to the disk. That way you could throw some ISOs into the Ventoy partition (right from the GUI file manager if you want to) and boot to Ventoy from Grub, or whatever boot manager.
It seems like it would be possible if Ventoy can share the regular EFI partition, but I have not tested or even looked at it closely. disk_layout_gpt . Ventoy
