Fix MBR or Operating System Not Found in Windows 7

Back when I first started playing with different Linux distributions, like Ubuntu, I’d accidentally wipe out the boot loader. I had been through this scenario in Windows XP countless times and I knew how to restore the Windows master boot record.

I ended up with a really weird message when I went to restart the machine. It wasn’t Operating System Not Foundbut I knew what had happened.

Fortunately, I had created a Windows 7 Repair disk. If you haven’t done this yourself, take a few minutes and do it now.
