Thanks for the link. I tried booting from an Ubuntu live USB last night and it's fine. It has internet so it might have just been a Mint issue or maybe I did a bad live USB for Mint. I'm going to do the Ubuntu dual boot on the weekend and spend some time learning my way around. From what I have seen initially, it's everything I need and more and nowhere near as intimidating as people make it to be. My computer usage is extremely basic (no gaming) so I might be confident to do a full boot and delete Windows within a month or so.
