A lot of my problems are from tinkering as well but that's why I am using linux, to control it better and tinker with it. Why won't I just use macos if I wanted something I can't tinker with? I think people lose sight if why Linux even exists to begin with, it is all about user control and ability to tinker/hack it.

I think better UX and more configurability would solve this stuff (from a friendly interface). The reason desktop/distro people won't do that is because it is considered bad UX practice to have too many decisions for the user. But imo, a Linux user would be an exception. In an ideal world, whoever decided to disable the boot flag in this case should have provided an easy to access distro/de setting to flip it back on.
