it feels like i'm still in /g/ with these types of posts

you went on a tirade about "windows bad, linux (aRcH btW!!!) best" without giving us any relevant information to help you with your "issue", other than the fact that you can game on your linux gaming laptop. you should've told that to your family member to at least try and convince them that gaming on linux is acceptable/good, maybe try to educate them about wine/proton and how performance may not be as good and some minor configurations may be needed, but that you could make it work. But nope.

also seriously, i mainly use linux myself, and i know this is a linux community, but we all know that windows "just works". it is also literally just a point and click on a gui even on the installer, it's that easy. reflash/rewrite the iso, or get another iso. that is my guess as to what you're fucking up
