The very moment Apple announced in 2006 that all new Mac models would come with Intel chips inside, the geeks and the bloggers started going nuts. “Let’s see,” they thought. “Macs and PCs now use exactly the same memory, hard drives, monitors, mice, keyboards, networking protocols, and processors. By our calculations, it ought to be possible make a Mac run Windows!”

Now, some in the Cult of Macintosh were baffled by the very idea. Who on earth, they asked, wants to pollute the magnificence of the Mac with a headache like Windows?

Lots of people, as it turns out. Think of all the potential switchers who are tempted by the Mac’s sleek looks, yet worry about leaving Windows behind entirely. Or the people who love Apple’s iLife programs, but have jobs that rely on Microsoft Access, Outlook, or some other piece of Windows corporateware. Even true-blue Mac fans occasionally look longingly at some of the Windows-only games, Web sites, or movie download services they thought they’d never be able to use.

Both techniques require you to provide your own copy of Windows. And both are described on the following pages.
