Oh, you're like me! I did the dive into Linux, SteamOS is a fork of Arch Linux which is super not newbie friendly.

Manjaro is a good Arch Linux fork that works well for gamers, though. Still not idiot proof, as I can atest to breaking it several times, but that's the deal when you remove the training wheels off your OS.

Lucky it's easy to reinstall from a USB. A little less if you insist on a duel boot like me, but that's mostly Windows being a jerk.
