I installed VMware fusion on my Mac and got it to boot my native installation of Windows but on boot up in the VM it crashed with a blue screen message STOP 00007B. Took me a while to find it but I actually followed some advice from Microsoft themselves which mostly fixed it. The missing piece to the puzzle was one of the sys files you need to copy over was in %SystemRoot%\Driver Cache\I386\sp2.cab (in addition to Driver.cab).
It works great but then I got asked to reactive windows - there seems to be a fix here.
