I'm quite the newbie at operating systems etc., so forgive me if my question is dumb. Is it possible to install Linux and Windows on a Mac, to run side by side with OS X? I'm about to start a new study, and I would like the new retina MacBook Pro for it, but for my study I'm definetely going to be programming C# and for that I'll prefer Windows. And I've recently started exploring C++, and I really love Linux and would like to make some apps for it, so that's why I'd like to have Linux on there as well.
Question summary: On a new retina MacBook Pro, is it possible to install Windows and Linux next to Mac OS X so I can choose which OS I want on boot?
