What worked for me was to manually copy the entry¹ from grub.cfg from the ISO to boot/grub/mbusb.d/pop-os.d/generic.cfg but that will break on the following release, so it would be nice to see if we can fix this in a generic way. If there is no such way, please remove this file to avoid confusion (it jumps back when you try to select the entry in the boot screen).

First of all thanks for forking the original repo. I really loved the tool and I'm glad to see someone is willing to maintain it for a bit longer.
Having said that, the latest Pop!_OS iso does not contain a
loopback.cfgfile (also see https://github.com/pop-os/iso/issues/243 and https://github.com/aguslr/multibootusb/pull/159 ), so this does not work, sadly.What worked for me was to manually copy the entry¹ from
