This may sound like a stupid question to some I'm sure. I'm generally very knowledgeable about this stuff. I currently have Gaming PC that is dual boot with Vista and Windows 7 RC. My neighbor recently bought a new Mac Pro and we're curious to see how it handles certain games. In theory, is it possible to just stick the Windows 7 RC hard disk into the Mac Pro and boot up just fine? after installing the mac drivers obviously... The disk in question is a brand new WD 1TB Black drive. the exact one sold on newegg for $95 I believe. EDIT: Obviously on the Mac Pro it would be under Dual Boot situation as well with OSX and Windows 7. He'd keep his OSX drive where it is and put my Windows drive in the slot next to it.
