The first thing you’ll need to do is boot off the install disc, and then click through until you see the “Repair your computer” link in the lower left-hand corner.

You’ll need to choose the correct installation of Windows and then click the Next button

And then you’ll get to the System Recovery Options screen, where you can get to the Command Prompt.

Repairing the Master Boot Record

If you want to restore the master boot record, you can simply type in the following command:
bootrec /fixmbr

You can also write a new boot sector onto the system partition with this command (which is often more useful):
bootrec /fixboot       (This is the same way that we fixed the “BOOTMGR is missing” error when trying to boot up Windows 7 or Vista.)

And of course, if you just use bootrec /? you’ll be able to see all the options.
