How to Fix Windows Master Boot Record or Disk Partition Table
Your Master Boot Record got damaged? This message sounds really pretty scary, but if your hard drive is still intact then don’t worry at all. In most of the cases you can fix this type of problem by following simple procedures to repair your Master Boot Record (MBR). Whenever you start your computer it looks for the MBR, which tells to the BIOS which partition of the hard drive has OS installed.

But fortunately you can recover or repair the Master Boot Record by using either the Spotmau Powersuite 2010 CD or the Windows XP Recovery Console.

- If your computer is prompting like press any key to start the booting from CD then do it immediately. If you not press any key, then it will try to boot from the hard drive.
- After Installing few files it will prompt like press R to start Recovery Console.
- Whenever this Recovery Console starts, it will ask you to enter the partition number that you need to repair in Windows XP. Most of the cases the number is “1.” After entering this number and pressing the “Enter” key it will continue with the setup. If you have not entered any number and pressed Enter then your computer will restart immediately by quitting from the installation of Recovery Console Program.
- After finishing that installation it will ask to enter your Administrator password. If you are not entering right password, you cannot continue for further.
- After entering right password it will open the Recovery Console command prompt, here type fixmbr command and then press Enter to continue the process.
At this point, the Recovery Console will create a new MBR and replace the old one. After finishing this repair, you can reboot your computer normally. In very rare cases you should repair the boot sector or disk partition table in addition to the MBR. If still you PC does not work properly then repeat those steps mentioned above and type fixboot instead of fixmbr command.
NOTE: If you are using the XP Recovery Console procedure, then it will assume that you have only one OS in your system. But, if you have more than one Operating System in your PC (e.g Windows and Linux), then you need to search for additional information to fix the problem of Master Boot Record or Boot sector by using the commands fixmbr and fixboot respectively.
