Fixing or creating the MBR

The MBR (Master Boot Record) is created when the first partition on a hard disk is generated. It is the most critical data structure on the disk, always located at track 0, head 0, sector 1. The MBR contains the partition table and a small amount of executable code that identifies the system partition, loads the Partition Boot Sector into memory, and transfers execution to it.

To fix or create a typical MBR:

  1. In the Active@ Partition Recovery workspace, select a disk from the Local System Devices list.
  2. From the Tools menu, choose Fix MBR (Create Typical MBR). A warning message appears.
  3. Click Yes.
The MBR is repaired.
