What partition style to use code#

MBR-based partition table schemes insert the partitioning information for (usually) four 'primary' partitions in the master boot record (MBR) (which on a BIOS system is also the container for code that begins the process of booting the system). Although it forms a part of the Unified Extensible Firmware Interface (UEFI) standard (Unified EFI Forum proposed replacement for the PC BIOS), it is also used on some BIOS systems because of the limitations of master boot record (MBR) partition tables, which use 32 bits for storing logical block addresses (LBA) and size information. GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk, using globally unique identifiers (GUID). A GPT can coexist with an MBR in order to provide some limited form of a backwards compatibility for older systems. Therefore, the MBR-based partitioning scheme is in the process of being superseded by the GUID Partition Table (GPT) scheme in new computers. The organization of the partition table in the MBR limits the maximum addressable storage space of a disk to 2 TB (232 Г— 512 bytes). This MBR code is usually referred to as a boot loader. Besides that, the MBR also contains executable code to function as a loader for the installed operating system-usually by passing control over to the loader's second stage, or in conjunction with each partition's volume boot record (VBR). The MBR holds the information on how the logical partitions, containing file systems, are organized on that medium. The concept of MBRs was publicly introduced in 1983 with PC DOS 2.0.

A master boot record (MBR) is a special type of boot sector at the very beginning of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond.
