Questions tagged [gpt]

The GUID Partition Table (GPT) is a method of partitioning disks. It features up to 128 partitions by default and it uses 64-bit pointers, which means it fully supports disks of up to 8ZiB, as opposed to the 2TiB limit of the older Master Boot Record (MBR) partitioning scheme. GPT is most often used on EFI-based computers, but it is sometimes used on BIOS-based systems, too.
