- ^ The GUIDs in this table are written assuming a little-endian byte order. For example, the GUID for an EFI System partition is written as {C12A7328-F81F-11D2-BA4B-00A0C93EC93B} here, which corresponds to the 16 byte sequence 28h 73h 2Ah C1h 1Fh F8h D2h 11h BAh 4Bh 00h A0h C9h 3Eh C9h 3Bh — only the first three blocks are byte-swapped.
- ^ The formation of this GUID does not follow the GUID definition; it is formed by using the ASCII codes for the string "Hah!IdontNeedEFI". Such formation of "GUID" value breaks down the guaranteed uniqueness of GUID.
- a b Previously Linux used the same GUID for the data partitions as Windows (Basic data partition: {EBD0A0A2-B9E5-4433-87C0-68B6B72699C7}). Linux never had a separate unique partition type GUID defined for its data partitions. This created problems when dual-booting Linux and Windows in UEFI-GPT setup. The new GUID (Linux filesystem data: {0FC63DAF-8483-4772-8E79-3D69D8477DE4}) was defined jointly by GPT fdisk and GNU Parted developers. It is identified as type code 8300 in GPT fdisk.
- a b The GUID for
/usron Solaris is used as a generic GUID for ZFS by Mac OS X. - ^ Definitions are in src/sys/sys/disklabel_gpt.h. NetBSD had used the FreeBSD GUIDs before unique NetBSD-specific GUIDs were created.
- ^ Definitions are in .
- ^ Definitions are in src/add-ons/kernel/partitioning_systems/efi/efi_gpt.cpp.
- ^ Definitions are in src/sys/sys/gpt.h. MidnightBSD had used the FreeBSD GUIDs before unique GUIDs were created.

Famous quotes containing the word type:
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
