I have an Acer Aspire One D250 which originally came with Windows XP.
When I bought it I needed to start using it fast, so I only made a copy (as in, copy all the files) of the original C drive to another drive, and then I installed Windows 7 and Linux on it (erasing everything that was on the drive before, including the Acer recovery partition).
Now I would like to sell it, so I'd like to put it back in the factory condition. Is there a simple way I can use the backup of the files I've made to restore it to the original condition, ie. reinstall Windows XP?
