Indeed. > GPT is a partition table. UEFI is booting. MBR is partitioning. MBR is both. The "B" in MBR stands for "boot". http://en.wikipedia.org/wiki/Master_boot_record With Legacy BIOS it provides the first custom x86 program code in the boot process. The MBR's partition table is supposed to play no role in the firmware's decision to start this custom x86 code. UEFI ignores the x86 code area in the MBR. It only looks at its partition table to decide whether a GPT is announced or whether the MBR partition table is to be used to find the EFI System Partition. A GPT is announced by a single MBR partition of type EE which covers the whole disk size from block 1 to its end. In this case, the disk block 1 contains the GPT header which tells position and size of the partition table. https://en.wikipedia.org/wiki/GUID_Partition_Table In both partition table cases of UEFI booting, one of the partitions contains a FAT filesystem with the initial program for booting. To confuse the world, it its the UEFI specification which contains the officicial specification of GPT. So hair-splittingly one could call UEFI a partitioning scheme, too. But then UEFI would also be MBR. Have a nice day :) Thomas
