Can I use Boot Camp to install Linux on my MacBook Pro?

Welcome to the Apple Support Communities

Boot Camp wasn't designed to install Linux. Apart from that, the Boot Camp version included in OS X Mountain Lion will ask you to insert a Windows 7 or Windows 8 DVD in order to run Boot Camp, as far as I know.

Apple doesn't support Linux on Macs, but it works properly on Macs. There are a lot of how-to's in the Internet about the steps to install Linux and the different possibilities you have. Also, what distribution do you want to install on the computer? You should also consider the option to install Linux on a virtual machine

You are welcome. Finally, you can find the steps to install Ubuntu on your Mac on a lot of sites, but I recommend you to search them in the official Ubuntu Forums > http://ubuntuforums.org/forumdisplay.php?f=328

You are welcome
