Most laptops have a secret partition on the hard drive called a RECOVERY PARTITION that is designed to help restore the operating system or do a FACTORY RESTORE back the way it was when it first came out of the box. I think that's what you're looking for.
On my laptop, when I first turn it on, of I start pressing F11 right away, it brings up the Recovery Console where I can accomplish this restore/recovery. I'm sure your laptop has something similar.
