I have a Toshiba laptop with a bad hd so I replaced the hd. I want to reinstall windows but obviously have no hidden partition left. They have recovery disk for $30 but I want to make sure I can reinstall from these before spending the money.
Get recovery disks and reload. You will lose all your documents, pics etc. You might be able to put your old drive into another computer as a secondary drive and retrieve docs from there to usb or dvd. you will need an adapter to put it in a desktop
