Another option if you have a laptop and desktop is to test the waters slowly with the laptop, and keep your desktop as is. It’s what I did for a long while to get used to things on Linux.
If there is a critical problem with my Linux instalation on my laptop, it’s OK because all the real stuff I care about is still on the desktop. So I’m free to wipe the laptop at a moments notice. It’s the easiest way to learn in my experience.
