I have made a multiboot USB stick using multibootUSB, but I can’t get it to work. I think this is because it starts in UEFI, and I don’t want it to boot into legacy mode anyway. It just gives me the grub> screen, which tells me I can press TAB to list all possible commands. It should work, but I don’t know enough about grub to actually make it work. So what I’d like to know is either how I can make the menu that lists all installed ISOs appear anyway, or how I can list and select them within the grub terminal screen. I tried to find this in the multibootUSB documentation, but I didn’t get beyond that it should be possible.
I hope someone can point me in the right direction.
