Setup Virtualbox on Ubuntu 16.04?05 Oct 2016
Virtualbox is a open source, well maintained virtual machine package that can install a huge array of x86 and amd64 operating systems
sudo apt install virtualbox -y
Once this finishes installation you should be able to launch Virtualbox from your app launcher.
BTW I created a video version of this tutorial for a more visual feel
I recommend watching in 1080p60 and fullscreen!
