how-to-clean-install-windows-the-right-way

Not a bad article, but if I was you I would get the bios key and go ahead and download a copy of windows even if you’re not planning on upgrading to windows 10, It’s just a way to get ahead of the dead hard drive problem most people run into. Did i also mention you need to have an external hard drive to store documents and pictures on, it would make the perfect place to store your windows 8 or 10 iso file with the key that you pulled from the bios.
