I'm not sure if mint is completely the same, but on Ubuntu you can easily make a bootable USB of another distro using this method: https://ubuntu.com/tutorials/create-a-usb-stick-on-ubuntu#2-requirements
You'd then back up your data, and restart your computer and then, depending on the computer, it might either start the distro installation or you'll need to go into bios and configure your computer to boot from USB.
It sounds more complicated than it is, but there are lots of online tutorials to show you how to do it. Just make sure to back up your data first just in case.
It's the game it should have been at launch. Everything feels a lot more fleshed out. There are still a tonne of bugs though but none game breaking.
