i have a Compaq presario 2100 labtop and I'm wanting to restore it to factory settings but i do not have the disk for it. Ive tried starting it up and pressing f10 and f11 like some other people have told me to do and nothing happens i don't know what else to try besides getting the CD and i really don't want to do that. is there anything else i can do before i go out and buy the CD?
