I don't know the standards, but it's obvious that at least one unexpected label/path interference causes problems, so it's better not to provoke another one which possibly affects only very few implementations, but causes needless trouble. Better use something like 'gpart add -t efi -l A-uefiLOADER -a 512k -s 512k <device>' (resulting in /dev/gpt/A-uefiLOADER to be used insteaad of /dev/gpt/efi for the following commands) I personally prefer the "A-" prefix is to describe that it's the 1st mirror component=E2=80=A6 Change it to whatever you like. >> newfs_msdos /dev/gpt/efi >> mount_msdosfs /dev/gpt/efi /mnt >> mkdir -p /mnt/efi/boot >> cp /boot/boot1.efi /mnt/efi/boot/bootx64.efi -Harry
