The MBR (Master Boot Record) is created when you generate the first partition on a hard disk. It is probably the most important data structure on the disk. The location is always track (cylinder) 0, side (head) 0, and sector 1.
The MBR contains the partition table for the disk and a small amount of executable code. On x86-based computers, the executable code examines the Partition Table, and identifies the system partition.
The MBR then finds the system partition's starting location on the disk, and loads a copy of its Partition Boot Sector into memory. The MBR then transfers execution to executable code in the Partition Boot Sector.
To fix or create a typical MBR:
- In the Active@ Partition Recovery workspace, in the Local System Devices list, select a disk.
- From the Tools menu, choose Fix MBR (Create Typical MBR). A Warning message appears.
- Click Yes.
The MBR is fixed.
Note: For more detailed instructions and support, see the Active@ Partition Recovery User Guide.
