@Frederic Hi, add the mkfs option;

<mkfs_options>-F 16</mkfs_options>

The disk should be gpt and MBR should be protective for UEFI now you can use legacy with gpt but require pmbr_boot (8MB)

parted -l /dev/sda
...
Partition Table: gpt
Disk Flags: pmbr_boot

Number  Start   End     Size    File system     Name  Flags
 1      1049kB  9437kB  8389kB                        bios_grub
 2      9437kB  53.7GB  53.7GB  btrfs                 legacy_boot

UEFI disk…

parted -l /dev/sda
...
Partition Table: gpt
Disk Flags: 

Number  Start   End     Size    File system     Name                  Flags
 1      1049kB  274MB   273MB   fat16           EFI system partition  msftdata
 2      274MB   54.0GB  53.7GB  btrfs           Linux filesystem

My bad Malcolm ! I used the partition, not the device : gdisk -l /dev/sda3 instead of /dev/sda !
So, no error raised ! Task is completed !
I’m not done with it because I still have to adapt all my installation type but I have a strong base now.
Thanks again for the help
