I am a little computer savy and remember something about new computers that come with Windows 8 cannot have Windows 7 installed because of something in the BIOS ???? I need to get a new computer (HP or Dell) and would like to remove the h.d that has Windows 8 and install a spare h.d. and install Windows 7. Is it possible and what are they talking about that the BIOS may not allow an install of Windows 7 on a new h.d. and what would I have to do to get Windows 7 installed. Hope this makes sense.
