GUID Partition Table (GPT) is a partitioning scheme that is part of the Unified Extensible Firmware Interface specification; it uses a globally unique identifier for qualifying devices. It is the next generation partitioning scheme designed to succeed the Master Boot Record partitioning scheme method. It evolved to deal with several shortcomings of the MBR partitioning scheme method and offers additional advantages.

See Partitioning#GUID Partition Table.

Kernel Support

CONFIG_EFI_PARTITION option in the kernel config enables GPT support in the kernel (despite the name EFI PARTITION). This options must be built-in the kernel and not compiled as a loadable module. This option is required even if GPT disks are used only for data storage and not for booting. This option is enabled by default in Arch's linux and linux-lts kernels in [core] repo. In case of a custom kernel enable this option by doing CONFIG_EFI_PARTITION=y.
