Hey Ludo!

The same one as you :)

Yep, that would be because of the Grub stripping issue. Regarding the
EFI, both the qcow2 and the efi-raw image types produce "hybrid" images
that have "grub" installed in the MBR-gap and "grub-efi" in the ESP
partition. This way, those images can be used both on legacy BIOS based
machines as well as on more modern UEFI machines.

Now the image types names can be confusing, and we could rename efi-raw
and qcow2 to pc-hybrid-raw and pc-hybrid-qcow2 respectively.

WDYT?

Thanks,

Mathieu
