Before recovering/restoring MBR, do you know what MBR is?
MBR, Short for Master Boot Record, a small program that is executed when a computer boots up. Typically, the MBR resides on the first sector of the hard disk. The program begins the boot process by looking up the partition table to determine which partition to use for booting. It then transfers program control to the boot sector of that partition, which continues the boot process. In DOS and Windows systems, you can create the MBR with the FDISK /MBR command. So, if there is something wrong with the MBR, say, if the MBR is infected by MBR virus, which replaces the MBR with its own code, the computer will fail to boot. In this situation, you need a partition recovery software for MBR recovery/restore to access to the computer.
Partition Table Doctor is just the solution for computer users to recover/restore the MBR when the computer failed to boot.
Rebuild MBR is the function of Partition Table Doctor for recovering/restoring MBR. Use this function to manually rebuild the master boot record (located on cylinder 0, head 0 and sector 1) when it was destroyed and the computer couldn"t boot from it.
Select "Rebuild MBR" on "Operations" menu or press "F7" key to recover MBR.
Notes: This function only rebuild "Main Boot Code" in the master boot record. If you want to recover partition, you can use Restore Partition Table or Rebuild Partition Table.
