Fix the MBR in Windows 7



If you have a Hard disk that does not boot for what ever reason here is a procedure to repair the boot partition
The below procedure saved me lots of time when I installed my drive on a later model motherboard that was not compatible with the boot partition on the drive

The instructions are:

  1. Boot from the Windows 7 installation DVD
  2. At the “Press any key to boot from CD or DVD…”, press any key to boot from the DVD
  3. Select a language
  4. Select a keyboard layout
  5. Click Next
  6. Select the operating system and click Next. The “Use recovery tools that can help fix problems starting Windows” must be checked when you select the operating system.
  7. At the System Recovery Options screen, click on Command Prompt

  8. When Command Prompt successfully loads, type this command: bootrec /rebuildbcd
  9. Press Enter
  10. Type the next command: bootrec /fixmbr
  11. Press Enter
  12. Type the next command: bootrec /fixboot
  13. Press Enter
  14. Remove the installation DVD from the disk tray and restart your computer
