If I’m performing a an upgrade to Windows 8, do I have to have the previous version installed, or is just having the key enough?

I have an old laptop with windows xp installed on it. It has a broken battery and I don't use it anymore. I have a new build coming up, and I'd like to have windows 8 on it. I have no idea where the original windows xp disk is that came with the laptop.

My question is: What is required to use that xp license for the windows 8 upgrade? Is there any way to upgrade to windows 8 pro, using the software upgrader or the more expensive dvd upgrade, that just allows you to plug in a valid windows xp key and upgrade? Or do those require you to run the upgrade on the existing install?

I think you can run the upgrade only on an existing install. –  VenkatH Nov 11 '12 at 18:29

As long as the key is not an OEM key then yes you can use it to upgrade from.

You'll have to actually install XP first - so you'll need to find that disk - and then install the Windows 8 upgrade.

Well it's a toshiba laptop. Would the winxp install be considered OEM? I did not buy it separately, it came with the laptop. –  ryeguy Nov 11 '12 at 18:32
    
@ryeguy - it will be an OEM key. You cannot use it on anything other than the original hardware. –  ChrisF Nov 11 '12 at 18:33
