|"it's an XP OEM so it doesn't have the option to make restore discs"? |
Actually most OEM computers DO allow you to make restore disks, ONE time.
The Restore Disks will restore the computer to the same EXACT state it was when it came from the factory. You should have those AND the types described below. Read your manual to learn how to create a restore set.
What you actually want is to create an image of the entire partition. Acronis is a good imaging program.
Below is a good deal on Acronis. Read which versions of Windows are supported by each version and use that info to make your buying decision.
