All PCs need us to create recovery media or order them when we forget. I have "Gateway laptop", "Windows 7" and not much else.
Be sure that all USB things are unplugged before performing a factory reset. I can't look up the exact steps for your laptop since the model number isn't here.

My son said that my computer had to be factory reset to get rid of the junk on my computer. But when he did it kept coming up with a message that the system cannot finish configuring windows. Now I am stuck with a useless gateway laptop that is supposed to have windows 7 that won't turn on because of this message. HELP. I need to do my taxes and stuff and can't do anything with no computer.
