Partition type

Table inside a master boot record

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.).

01Overview

Lists of assigned partition types to be used in the partition table in the MBR were originally maintained by IBM and Microsoft internally. When the market of PC operating systems and disk tools grew and liberated, other vendors had a need to assign special partition types to their products as well. As Microsoft neither documented all partition types already assigned by them nor wanted to maintain foreign assignments, third parties started to simply assign partition types on their own behalf in a mostly uncoordinated trial-and-error manner. This led to various conflicting assignments sometimes causing severe compatibility problems between certain products.

Several industry experts including Hale Landis, Ralf D. Brown, Matthias R. Paul, and Andries E. Brouwer in the 1990s started to research partition types and published (and later synchronized) partition type lists in order to help document the industry de facto standard and thereby reduce the risk of further conflicts. Some of them also actively helped to maintain software dealing with partitions to work with the updated lists, indicated conflicts, devised additional detection methods and work-arounds for vendors, or engaged in coordinating new non-conflictive partition type assignments as well.

It is up to an operating system's boot loader or kernel how to interpret the value. So the table specifies which operating systems or disk-related products introduced an ID and what file system or special partition type they mapped it to. Partitions with partition types unknown to the software should be treated as reserved but occupied disk storage space which should not be dealt with by the software, save for partition managers.

02Local or Experimental Use

While the list is not officially maintained, new assignments should be coordinated.

In particular temporary partition type assignments for local or experimental projects can utilize type 7Fh in order to avoid conflicts with already assigned types. This type was specially reserved for individual use as part of the Alternative OS Development Partition Standard (AODPS) initiative since 2002.

03List of partition IDs

This is a list of known master boot record partition types on IBM PC compatible computers:

Disk partitioning

Disk partitioning or disk slicing is the creation of one or more regions on secondary storage, so that each region can be managed separately. These regions are called partitions.

Extended boot record

An extended boot record, or extended partition boot record (EPBR), is a descriptor for a logical partition under the common DOS disk drive partitioning system. In that system, when one (and only one) partition record entry in the master boot record (MBR) is designated an extended partition, then that partition can be subdivided into a number of logical partitions.

GUID Partition Table

The GUID Partition Table is a standard for the layout of partition tables of a physical computer storage device, such as a hard disk drive or solid-state drive. It is part of the Unified Extensible Firmware Interface (UEFI) standard.
