OS support of GPT

Hybrid MBRs are non-standard and can be interpreted in different ways by different OSes.^[9] Unless otherwise noted, OSes provide precedence to the GPT data when a hybrid MBR configuration is encountered.

The term No native support on this arch and version. should be understood this way:

Not supported as data disk^[10], only known legacy partitions found in protective MBR are accessible via the OS. Detachable disks: only support for MBR partitioning; No access with end user applications. GPT contained raw data is accessible with third-party administrator tools for low level disk access. True file system level support in read or read-write form might be subject of software from a third-party vendor.

[edit] Unix-class operating systems

OS	Version/ edition	Platform	Boot from GPT on PC/BIOS	Boot from GPT on EFI	Note
FreeBSD	Since 7.0	x86, x86-64	Yes	Yes	In a hybrid configuration, both GPT and MBR partition identifiers may be used.
Linux	Most of the x86 Linux distributions Fedora 8+ and Ubuntu 8.04+[11]	x86, x86-64	Yes	Yes	Some distribution tools, such as fdisk, don't work with GPT. New tools such as gdisk,[12] Syslinux, grub .96+ patches and grub2 have been GPT-enabled.
Mac OS X	Since 10.4.0 (some features since 10.4.6)[13]	x86, x86-64	Yes with bootloader (hackintosh)	Yes
Solaris	Since Solaris 10	x86, x86-64, SPARC	No (work in progress)	No (work in progress)

[edit] Windows 32-bit versions

Microsoft does not support EFI on 32-bit platforms, and by extension, does not allow booting from GPT partitions.

OS	Version/ edition	Platform	Boot from GPT on PC/BIOS	Boot from GPT on EFI	Note
Windows XP	(2001-10-25)	x86	No	No	No native support on this architecture and version.
Windows Server 2003	(2003-04-24)	x86	No	No	No native support on this architecture and version.
Windows Server 2003	(2005-03-30)	x86	No	No	Data Disk only [10] MBR takes precedence in hybrid configuration.
Windows Vista	(2005-07-22)	x86	No	No	MBR takes precedence in hybrid configuration.
Windows Server 2008	(2008-02-27)	x86	No	No	MBR takes precedence in hybrid configuration.
Windows 7	(2009-10-22)	x86	No	No	MBR takes precedence in hybrid configuration.[9]

[edit] Windows 64-bit versions

The following table lists only the 64-bit Windows versions that support GPT. These were the "64-bit" server editions for the IA-64 processor platform that came with EFI and GPT boot support on release as GPT was the default partitioning type with increasing features in the peripherals. The "x86" editions for servers and for end users for the x86-64 and EM64T processor platforms initially only had very limited GPT support until mainstream Windows variants reached parity with the IA-64 variants on the release of Windows Server 2008. Please note that below are several so-called "Windows XP" versions listed that in fact are technically more equivalent with the mentioned Windows version in the second column.

OS	Version/ edition	Platform	Boot from GPT on PC/BIOS	Boot from GPT on EFI	Note
Windows Server 2003	(2005-03-30)	x86-64	No	No	Data disk only[10] MBR takes precedence in hybrid MBR configuration.
Windows XP	(2005-04-25)	x86-64	No	No	Data disk only[10] MBR takes precedence in hybrid configuration. Detachable disks: only support for MBR partitioning.
Windows Vista	(2005-07-22)	x86-64	No	Yes	MBR takes precedence in hybrid configuration.
Windows Server 2008	(2008-02-27)	x86-64	No	Yes	MBR takes precedence in hybrid configuration.
Windows 7	(2009-10-22)	x86-64	No	Yes	MBR takes precedence in hybrid configuration.[9]
Windows Server 2008 R2	(2009-10-22)	x86-64	No	Yes	MBR takes precedence in hybrid configuration.
