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 ...
A memory buffer register (MBR) or memory data register (MDR) is the register in a computer's CPU that stores the data being transferred to and from the immediate access storage. It was first implemented in von Neumann model .
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.
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 ...
MBR may refer to: Science and technology ... Minerações Brasileiras Reunidas, an iron mining business; See also. Movimiento Bolivariano Revolucionario 200 ...
Near the end of the MBR is the Partition Table: a predefined structure containing the layout of the disk. Track0 is also increasingly used to store licensing information for particular pieces of software because it is an area of the disk outside of the OS filesystem and not seen or used by most computer users (and therefore cannot be easily ...

Like MBR, GPT uses logical block addressing (LBA) in place of the historical cylinder-head-sector (CHS) addressing. The protective MBR is stored at LBA 0, and the GPT header is in LBA 1, with a backup GPT header stored at the final LBA.
