I recently finished building my first PC. All I need to do is install Windows 7. I have it on disc and I have an Optical Drive. When it starts it's download it gives me all these different blue screens. It says the SSD and HDD are in MBR and need to be PGT. How do I do that without the OS installed? I have an old PC with VISTA on it. Should I take the HDDs from that and install 7 to that then switch the 7 to my SSD? I've spent a lot of money on my components and don't want to ruin anything. Please help!
