My brother is 12 and just like other people of his age he can’t use a computer properly because he is only familiar with mobile devices and dumbed-down computers
I recently dual-booted Fedora KDE and Windows 10 on his laptop. Showed him Discovery and told him, “This is the app store. Everything you’ll ever need is here, and if you can’t find something just tell me and I’ll add it there”. I also set up bottles telling him “Your non-steam games are here”. He installed Steam and other apps himself
I guess he is a better Linux user than Linus Sebastian since he installed Steam without breaking his OS…
The tech support questions and stuff like “Can you install this for me?” or “Is this a virus?” dropped to zero. He only asks me things like “What was the name of PowerPoint for Linux” once in a while
After a week I have hardly ever seen my brother use Windows. He says Fedora is “like iOS” and he absolutely loved it
I use Arch and he keeps telling me “Why are you doing that nerdy terminal stuff just use Fedora”. He also keeps explaining to me why Fedora better than my “nerd OS”
Is it possible but you could run into issues. You can shrink that drive and leave space for Linux there, but be careful while setting up your partitions so you don’t accidentally erase your games data.
Its always easier to use a whole drive so you don’t have to worry about partitions. I’ve never done what you’re describing but it shouldn’t be much of a hassle.
