Partition type
Table inside a master boot record / From Wikipedia, the free encyclopedia
This article is about MBR partition types in IBM PC compatible systems. For GPT partition types, see GUID Partition Table § Partition type GUIDs. For Amiga RDB partition types, see Rigid Disk Block.
The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file systems, etc.).
