Can I install Linux and Windows on a Mac to triple boot the hardware? 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?
It's possible to install them in multiple partitions and multiboot. But the resulting setup will be a little "rigid".

Doing OS X and Windows is easy. Adding Linux to the mix is a little more complicated.

I suggest you do not multiboot and only install OS X as the main OS and then use a virtualization solution, like Parallels Desktop or VMware Fusion. With those you can basically run a whole operating system, like Windows or your favorite Linux distribution, as if they were OS X applications.
