From the same guys who brought you Ubuntu right on your OS X desktop, a new guide tackles installing the PC newest flagship OS, Vista Ultimate, into your very own Mac box - more appropriately, your MacBook Pro.

Now the capability of Apple's newer systems to run Windows isn't new news: Apple's move to Intel has made that possibility a lot easier to imagine.

But installing Windows instead of OS X is a lot different from installing Windows on OS X. Simplehelp presents a step-by-step guide for installing an OS over another OS, using a nifty little Virtual Machine (VM) software, called Parallels Desktop for OS X.

It was done before, yes, but this time it's the monster pack Ultimate that gets touchy-feely with its Apple side. Of course, there are problems that will ensue from installing Vista Ultimate on Mac (including hardware requirements).

So run over to the "Read" link and see how to do it. Remember, you will need Parallels Desktop and any Mac similar to a MacBook Pro, so the procedures will pretty much stay the same.
