If you are keen to test out a distro but do not have an ssd (faster than a harddisk) or harddisk to spare, you can install it in a virtual machine. You can use either vmware player or virtualbox.

But if you want to give VirtualBox from Oracle a go, you can follow this tutorial.

The script I use to install VirtualBox is coming from my github but you can download the latest one here as well. Choose Ubuntu 16.04 Xenial i386 or amd64.
