edit: for anyone curious, the problem was Xorg wasnt loading or something (stuck on systemd 'graphical interface target reached' with no graphical interface). because of a typo in a config file.
I have only really done this while i used windows, on linux i have always been able to find a solution that didn't require reinstalling; on windows on the other hand i had a time where it just started to bluescreen at every boot out of nowhere...
Meanwhile I've had Linux distros just completely bork themselves 20 minutes after install. Or during an update. Or while running a terminal command, because the "friendly" Linux community refused to give me GUI instructions, or simply explain what the command did.
They should explain what the commands do. Nobody should be blindly copy-pasting commands into their terminal.
Also, consider the source. Advice you get from Stack Overflow is going to be better than what you get from some random you DMed who said they were a "Linux ninja".
