GRUB can boot from GPT just fine. Assuming you are booting in EFI mode,
it just has to have an EFI system partition, and be registered with the
EFI firmware. You can't just copy the partitions to a new drive and
remove the old drive and expect it to boot. You will need to
grub-install on the new drive to register it with the EFI firmware.
