Hi,
the method in the article will not work for GPT partition tables that do not contain BIOS boot partitions (new hardware, UEFI).

Actually, if you use UEFI, you do not need a BIOS boot partition but rather an EFI System Partition (ESP), which is not the same thing. Only those using traditional BIOS with GPT and Grub 2 need a 'BIOS boot partition'. I have written another article about using GPT with BIOS. Perhaps ryanpcmcquen could link his article to mine, to assist such users?
