Windows 7: How do I restore the Master Boot Record?

How do I restore the Master Boot Record?

I deleted Ubuntu Linux from my computer by deleting the partitions that contained it, but this also deleted GRUB and now my computer can't boot into Windows.

I looked online and it said I needed the Windows 7 disk to restore the Master Boot Record. I do not have the Windows 7 disk.

People also said that a disk called "Hiren's Boot CD" would also work. I obtained this but I don't understand how to use it. Does anyone here know? Apparently there is a program called "mbrfix" or "fixmbr" or one of those but I have no idea how to access it or how to make it work.

What should I do?

Download the 64 bit system repair disk from this site.

System Repair Disc - Create

Boot from the disk, choose command prompt then type the following commands one by one. Hit Enter after each.

Bootmgr is missing - Fix

Bootrec /fixmbr
Bootrec /fixboot
Bootrec /rebuildbcd

Now boot normally.

This can be done from Hiren also, locate the command prompt option in it.
