My computer could not find its boot device after taking a closer look the hard drive is gone, making the good old dead header noise. So I got a new Hard Drive and tried installing Windows 8.1 and Windows 8 Pro both installed and worked but keep asking me for the key. The key is BIOS bound at least that is what I think. Is there anyway to pull that key or is there a certain media that I have to install so it fills in the Windows Key? Any light your can shed on this would be greatly appreciated, Thanks in advance
