I don’t disagree that installing windows/macos and certain Linux distros can be stupid easy but to a layman it’s daunting.

In my experience most people who use a computing device may be able to tell me “this is window” or “this is Mac” by virtue of the branding being all over the stuff but for all intents and purposes these things are appliances.

In the same way most people except ambitious DIYers don’t rip apart their 500-1000 dollar washing machine to replace a worn belt the call a repair guy. Or in your case, have a buddy who knows how to do it.
