Ok so I know the windows 8 product keys are now stored in the bios and I have a question about reinstalling it on the same computer just a different hard drive. I have a solid state drive I boot as my primary drive with windows 7 and a secondard hard drive that I have windows 8 installed on, im thinking about changing my primary solid state drive to windows 8.1 and just keeping that as my new os. My question is if I still have windows 8 installed on the second drive can I just do a windows.old for 7 and it will use the same key, then delete it from the secondary hard drive? Or if I was to delete windows 8.1 off my secondary drive first and then do a windows.old on the ssd would It automatically use the right key?
So if I just delete windows 8.1 from windows 7 then install 8 to the same hard drive to make windows do a .old for windows 7 (as you can't have two os's on the same drive)? Its windows 8.1 with media center.
And it wasn't a stock os, I got a key and installed it post build.
