I found this table at Boot Camp: System requirements for Microsoft Windows operating systems Good news for me is that Boot Camp supports nMP, bad news is that it supports only Windows 8. Last year, I install Windows 8 on two of my PCs and I was so disappointed by its very bad user interface for the people who were so much familiarized with Windows 7 or XP. After a short trial, I decided to reinstall Windows7 on one PC. Recently, I tried Windows 8.1 on the other PC. Windows 8.1 is little better, but far from satisfaction. And finally I reinstall Windows 7 on this PC also. ( I still have these unused Windows 8.) So, I was planning to use Windows 7 on my nMP and I actually bought a Windows 7 professional for this purpose, last week. I should wait until I see this information. It looks like I had to use Windows 8.1 on Boot Camp. So I use it only when the application requires full HW access, but I will usually use Windows 7 by VMWare Fusion, in parallel with OSX.
