Hello everyone! I've tried hunting through the forums, but I was getting somewhat confused with everything, so please bare with me. I have a Toshiba laptop that I purchased which came with the Windows 7 (had Vista already on it)upgrade. What I am wanting to do is use the Toshiba upgrade disc to install Windows 7 on a completely separate desktop PC (homebuilt). How do I go about this? Can I just use the upgrade key guide stickied on the forum, or do I need to modify my BIOS and all of that stuff? If yes, how the heck do I do that? Thanks!
