+This was by far the hardest part. Because UEFI and GPT a relatively new, I am not so familiar with it and the documentation isn't so good at the time of writing.

 If it finds one it tries to start {{path|/EFI/boot/bootx64.efi}} from this partition. (Note that this is actually case-insensitive because of FAT32).
