I started using linux by setting up a dual boot: using windows only for things I couldn’t do at the time on linux. That were gaming and some apps only supported by windows After usig it for some time I now have everything on linux (or an alternative) and uninstalled windows. Still in the process of figuring out some very specific stuff like you with your Quest, but someday I just couldn’t have it with windows anymore.

There are a lot of ressources online and some distros are really great for gamers/ newcomers. Just give it a try and some time. You will have to learn some things like you had to with first using windows.
