So... I have this Gateway laptop with Windows Vista on it. I want to sell it, so I'm going to reinstall windows to wipe the thing mostly clean for it's new future owner. I wasn't given a disc when I purchased the computer, nor did I make a backup disc. Several months ago I reinstalled Windows on the thing, but I can't remember how I did it. And now, I can't figure it out. I tried restarting and pressing F11 or F8 to access a secret partition, but nothing happens, nor can I find a secret partition in Windows itself. I'm stumped! Any ideas?
