My hard drive went on a fritz in the middle of updating Windows and cannot operate it. I will be getting a new drive and re-install but my only question is, will I have to buy a new copy of Win10 or is there a way to maintain my current copy. It was an upgrade from Win7. It would be highly frustrating if I need to buy it, but in the event of, would there be any problems if I bought that copy from Kinguin? I hardly find fair to have to pop $100 because of a (supposed) failed drive, which I actually think is still healthy. But besides that, I have no choice--Windows won't boot, I'm locked and I will upgrade. Can someone provide any useful links as to how I can maintain my current copy if possible? Please only reply with help to install Windows. Thanks.
