you need to be very careful with this...
you can only run 64bit on a 64bit processor...
if you have a PowerPC then you need to load a virtual machine that supports i386 emulation, but you will only have pseudo-32bit processing..
if you have an intel processor you can install the Windows for OS-X that gives you a start button at the bottom of your screen, you can run Windows Apps natively in OS-X.
But you can also get Windows to run on Linux... so end of the day... it's all the same... except now Windows runs in a window...
