EFI system - GPT

For EFI systems GPT is mandatory but does not have the restrictions explained above. The only requirement is to have a bootable partition (EFI System Partition) of type FAT32 and with enough size to store the EFI drivers. 500MB should be enough to store a bunch of them:

parted> mktable gpt parted> mkpart fat32 0% 500M parted> set 1 boot on parted> quit

dd if=/dev/sda1 of=/dev/sdb1 bs=64K
