Dead easy with Mint. I’ve been running it full time on my laptop for months now and my wife only recently came to find out it wasn’t windows when I was explaining Linux to her (and she’s not a technical personal - she’s the person who yells at TV remotes when they don’t work). Installation is super easy, much like installing windows - answer a few questions and off it goes. You can even install it alongside windows and pick what one you want to run on boot (I did this because of a couple windows-only apps I can’t ditch just yet). If you can figure out Lemmy, Mint will be a breeze too.
