There is no boot disk to restore to original windows, and I've tried some of the advice on this website like "Holding 0 until the Toshiba logo apears then tapping 0 until it goes away" and the HDD RENEW thing poped up but then it just loaded windows, so I'm guessing there's no partition either, unless there's another way of ressetting to the factory OS so I have a legal copy of windows?
It's a Toshiba Satellite P305-S8854
