I have an acer one we bought used so the kids can use it. It was running slow and full of pop ups so I decided to restart it to factory settings...and it just says failed. pressing the ok and ntldr is missing comes up. Reading other forums I have learned I need a disk for reinstalling windows xp. don't have one...hell this notebook don't even have a spot for a disk to go. So is this computer toast or can I use a usb stick on another computer to reinstall windows xp and if so what is the process to doing this. Thanks
