Hey everyone, so I am buying a used Motherboard from a local guy that had windows installed with it already. I also have a used hard drive from an old PC with the same version of windows. I know there will be issues with drivers being different and everything. But would it be possible to put the used hard drive in and let windows repair the missing drivers itself. or would it be better to just buy and re install windows 7 from scratch and do the free upgrade to windows 10?
