I have a Acer laptop which has Win XP installed. It's hard disk has gone bad. The laptop did not come with a recovery disk but instead had a Windows recovery partition on its hard disk. If I buy a new hard disk while the rest of the components remain the same how can I recover and use the licensed Windows which came with the laptop ?
There should be a license code on the bottom of your laptop, on a sticker. You should be able to call Microsoft or Acer and tell them about your problem. With that license code, and a copy of Windows xp, you should be able to reinstall on another drive.
