Alright, I'm replacing all Components in my PC but the RAM and the HDD. I cannot get to the BIOS for my current motherboard because of a manufacturer Windows 8 Lock. I bought a copy of Win8 to install in this new set-up. My Question is, I'm afraid that when I put everything together that the PC will start into the old Windows 8 instead of starting from the DVD drive. Though, even if it does, it should be easy enough to install Windows, I was hoping I wouldn't have to let the old Windows load. Is there anyway to do this?
