I am working on a Toshiba Satellite C855D (Windows 8 originally) that would not boot. I tried the repair, restore, and recovery but that did not work. So I used a recovery disc from a Toshiba C55D (Windows 8.1) and got it working. The problem I have is the c855d now shows as the c55d. My question is does the product key come from the motherboard or the software. I am working on the c855d for a friend. Thanks
