Ok, this should do it. It checks if isoinfo exists, and warns about the partition format.
the "lz problem" is solved, as it now gets the name from the ISO. Thanks, oshunluvr
It's still in "testing" mode, it doesn't actually write /etc/grub.d/40_custom or update grub, so feel free to play with it. It still needs the service menu for the ISO name :·)
