Linux mint
Thanks for the rec!
causes issues on the same drive in my experience
How so? I'm dual booting SteamOS + W10 on my Steam Deck right now, and the only issue I'm having is Windows changing the boot sequence. Probably could have fixed that if I flashed W10 first then SteamOS, but meh.
Lots of my family already run W11 by default, so I wouldn't think dual booting would be difficult.
what’s the benefit?
The idea is to give them Linux so they can try it out without committing full time since it's an entire process to de-Google and de-Microsoft people's lives. And to jump back to W11 because that's what they're used to.
boot into Linux by default
This to me is forcing them to use Linux, which is not what I want to do. I want them to explore it if they want.
There will be instances where a bug in W11 comes up and makes their lives fucking hell for the short time being. If Linux is right there as an alternative and just works, that will be a bigger motivator than me just installing in on their machine because I know what's best for them.
