A master boot record (MBR), or partition sector, is the 512-byte boot sector that is the first sector ("LBA Sector 0") of a partitioned data storage device such as a hard disk. (The boot sector of a non-partitioned device is a Volume Boot Record. These are usually different, although it is possible to create a record that acts as both; it is called a multi boot record.)
The MBR may be used to hold a disk's primary partition table. The MBR is not located in a partition; it is located at a Main Boot Record area in front of the first partition.
