New User, What is the best method to Install Ubuntu on my MacBook Pro (15-inch, Mid 2012)?

Hello!
I'm a new member and new to the Linux OS , I'm taking a Linux college course. Our class just started and we learned some things about Linux and I was eager to install it to my Macbook Pro but I didn't want my new download of Ubuntu to interfere with my current operating system because I need it for my other online courses. I was hoping I could create a dual boot to have the option to launch Ubuntu or the original Mac Operating system but I'm not sure how to do that with Mac OS boot camp utility or if that is even an option for installing Ubuntu.

 

I would suggest to install it in a virtual machine like virtualbox:

Is slower than a bare metal install, but does not affect your current installation.
