Okay, I have a 500gb hard drive in my desktop computer and it has windows 7 on it. I had a different hard drive to start with on this computer it was 150gb or something and it had vista so i just bought a different hard drive because it was too small to run vista well. Now that drive does have windows 7. So I wanna put that old hard drive back in the computer as a secondary drive to hold like music and photos and such. When I hook it back up windows starts that one instead of the newer 500gb.
Does anyone know how to fix this problem.
