    What Is MBR

    MBR (Master Boot Record) is a special type of loader code at the very beginning of computers’ hard disk. It contains an operating system bootloader and the storage device’s partition table. When DOS reads hard disk, MBR will help to check whether the partition is legal and locate the partition boot information.

    And, the loader code is variable. Thus, users can boot MBR from multiple operating systems. It can be found in FDISK program. MBR will pass the control over to the certain operating system which has been registered in the partition table.
