efi_gop is a driver for EFI graphics. It is available only in EFI mode, 
not in PC BIOS mode. I guess GRUB PC and GRUB EFI share the same 
grub.cfg config file which was generated for EFI mode and includes an 
"insmod efi_gop" command.

So the message was displayed by the BIOS which is non compliant. A 
compliant BIOS should not care about the partition table.
