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.
