These are the infos for the FAI ISO created by the patched fai-cd script after writing it to an USB stick (/dev/sda). The script uses -appended_part_as_gpt -append_partition 2 0xef $scratch/efiboot.img
In the boot menu list it shows as UEFI OS (< and description of USB stick>) and boots fine into linux with UEFI mode $ blkid /dev/sda2: SEC_TYPE="msdos" UUID="B3E0-35D0" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="Appended2" PARTUUID="99298f2b-1c15-41c1-ac2a-655adae72156" /dev/sda3: PARTLABEL="Gap1" PARTUUID="99298f2b-1c15-41c1-ac2b-655adae72156" /dev/sda1: PARTLABEL="Gap0" PARTUUID="99298f2b-1c15-41c1-ac29-655adae72156" $ fdisk -l /dev/sda GPT PMBR size mismatch (848223 != 1000215215) will be corrected by write.
