Solved: best method of testing Win 8 on my Win 7 pc

I love my Win 7 Pro x64 but I am getting tempted to try Win 8 Pro x64 again. I have wiped a hard drive so I could install Win 8 if you believe that is the best way of testing. I shall keep Win 7 until I believe there is a better alternative but I need to keep testing. Should I install it on a seperate hard drive or install it on a partition of my C drive. If I install it on my D drive I understand there are aggravating boot up problems and if I don't like it then there can be problems of removing it. What do you recommend and I'll try your way, scottspa. My computer details are:-
