According to UEFI specification all EFI platforms must support GUID Partition Table(GPT) disk layout. Here is a list of advantages of using GPT disk layout over the legacy MBR partitioning: - Logical Block Addresses (LBAs) are 64 bits (rather than 32 bits). - Supports many partitions (rather than just four primary partitions). - Provides both a primary and backup partition table for redundancy. - Uses version number and size fields for future expansion. - Uses CRC32 fields for improved data integrity. - Defines a GUID for uniquely identifying each partition. - Uses a GUID and attributes to define partition content type. - Each partition contains a 36 character human readable name. Used GPT partitioning in all EFI kickstart files. Tested result images on NUC, MinnowBoard MAX and MinnowBoard Turbot.
