A master boot record (MBR) is a type of boot sector in the first block of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond. The concept of MBRs was publicly introduced in 1983 with PC DOS 2.0.
According to Microsoft, the basic data partition is the equivalent to master boot record (MBR) partition types 0x06 , 0x07 (NTFS or exFAT), and 0x0B . [2] In practice, it is equivalent to 0x01 , 0x04 , 0x0C (FAT32 with logical block addressing), and 0x0E (FAT16 with logical block addressing) types as well.
The first sector of Track0 is known as the master boot record (MBR) and contains the initial code used to boot the operating system (bootstrap code). Near the end of the MBR is the Partition Table: a predefined structure containing the layout of the disk.
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 ...
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. It may contain code to load an operating ...
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.

MBRWizard is a Master Boot Record (MBR) management application for x86 and x86-64 based computers. As the use of disk imaging applications for backup and operating system deployment began to increase, as well as many users beginning to experiment with dual-booting Linux on existing Windows machines, key entries in the MBR were often changed or corrupted, rendering the machine unbootable.
