Hi Paul, GPT and DOS partitioning are totally different. GPT uses 128-bit GUIDS to identify partitions. DOS partitioning uses 8-bit IDs. In order for GPT partitioning to coexist with programs that only know about DOS partitioning, the UEFI spec mandates the use of the EFI Protective partition (type ee) that occupies the entire disk. You CANNOT have other DOS partitions on a disk partitioned with GPT. You can, however, create multiple GPT partitions by specifying the GUID (though I confess I haven't looked at the DTD and I'm not sure if you can specify arbitrary GUIDs-- Niall will know).
