I own and have properly installed Win7 Pro x64 on physical drive C:.
I've separate physical drive D: which was previously used in a dual-boot with Win 8 Enterprise Eval, now elapsed.
I plan to re-format (~blank) physical drive D:
I then want to purchase/install Win8 Pro x64 on drive D: so as to again provide the dual boot setup.
If I purchase Win8 Upgrade, will I be able to achieve the setup per above ?
What is the recommended MS Product Name/# for purchase & url for purchasing directly from MS ?
