Re: Ubuntu 16.4 gnome
Just a quick note which probably won't help, but it's bit me a few times: If you have anything plugged into the USB ports on your machine (aside from the drive you may be booting from), this can interfere with the installation process of any OS.
Especially Logitech wireless dongles.
I've used both Ubuntu and Mint, and my personal preference is Mint for the past few years. Considering Mint is a fork (kind of a 'child of') Ubuntu, both distributions work similarly, but I'd agree with @pete.i that Mint is a bit easier to get the hang of.
