This is analogous to the conversion from partition types 0x01, 0x04, 0x06, 0x07, 0x0B, 0x0C, and 0x0E to partition type 0x42 on MBR partitioned disks. Linux used the same partition type GUID for basic data partition as Windows prior to introduction of a Linux specific Data Partition GUID 0FC63DAF-8483-4772-8E79-3D69D8477DE4 .
On MBR disks, such boot loaders typically use the sectors immediately following the MBR for this storage; that space is usually known as the "MBR gap". No equivalent unused space exists on GPT disks, and the BIOS boot partition is a way to officially allocate such space for use by the boot loader.
Details of GPT support on UNIX and Unix-like operating systems OS family Version or edition Platform Read and write support Boot support Note FreeBSD: Since 7.0 IA-32, x86-64, ARM: 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+ [17] IA ...
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 ...
This section describes the master boot record (MBR) partitioning scheme, as used historically in DOS, Microsoft Windows and Linux (among others) on PC-compatible computer systems. As of the mid-2010s, most new computers use the GUID Partition Table (GPT) partitioning scheme instead.
A MBR program may interact with the user to determine which partition on which drive should boot, and may transfer control to the MBR of a different drive. Other MBR code contains a list of disk locations (often corresponding to the contents of files in a filesystem) of the remainder of the boot manager code to load and to execute. (The first ...

The MBR sector may contain code to locate the active partition and invoke its volume boot record. A volume boot record (VBR) is the first sector of a data storage device that has not been partitioned, or the first sector of an individual partition on a data storage device that has been partitioned.
