In high school, my friends and I were getting into Ubuntu. We were smug Linux nerds. We came up with the idea of installing Linux on one of the school computers. The challenges in doing so was, how to do so without the teacher noticing and getting into the locked bios. The teacher problem was solved when we got a little bit of time when the teacher would step out of the room sometimes. We picked a desktop that wasn't being used by anyone at the time in the class. The other problem was getting into the bios to boot the drive. Long story short, we were able to switch a jumper on the motherboard to clear the bios settings and let us boot the drive. With Ubuntu installed, it took all of about a day for the school to take that PC to the IT gulag. I think they were very confused and threw it out. We didn't want them to just throw more desktops out so we stopped our shenanigans there.
