You _may_ find that, if you boot from UEFI only and select expert mode, that it will work out of the box. I did this the other day and on my hardware (Zotac Zbox AD06) I did not need to hand create a GPT partition. The auto-partitioning mode created a 1MB partition at the beginning and end of the disk and a 512MB partition for the EFI boot. If done this way booting from UEFI at the beginning, you should get only grub-efi installed. > 4. create TWO partitions right at the begging of the disk: > 4.1. the first with 1Mib must be left unformatted and flagged as > Reserved space for boot (my understanding is that this area is used to > guaranteed that in the end, when grub is installed to MBR, it does not > overwrite our GPT scheme); > 4.2. the other one must be formatted as FAT32 filesystem and needs to be > greater than 32MB (?
