Does this mean that the decisive trick is to use GPT with EFI partition
instead of a MBR partition of type 0xEF ?
Or is there something missing in the FAT filesystem images of e.g.
Debian installation ISOs like
https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-9.3.0-amd64-netinst.iso
?
Michel: Does a simple ISO "output.iso" work, when made by
mkdir ./minimal
echo dummy >./minimal/dummy
grub-mkrescue -o output.iso ./minimal
and then copied onto the plain USB stick device (e.g. /dev/sdc) ?
grub-mkrescue produces valid GPT in ISO 9660.
Have a nice day :)
