The school doesn’t let you do that. Because if you installed Linux you could install games, and then you might get distracted. Never mind the fact that YouTube is still completely available.

I looked into this back when I was in school and there was some weird workaround found by someone on reddit that essentially forced it to do a complete factory reset. I didn’t want to get in trouble for doing that, and if I did that I wouldn’t have been able to connect to the wifi anymore.
