Getting Linux on an Obscure Chromebook

Alright, so basically, I have this really old Chromebook from 2014 i got from e-waste management, and I’d like to install literally anything other than ChromeOS on it. It stopped recieving updates 5 years ago. The thing is, however, it’s an enrolled chromebook. I have no contact with the school board who used to own it, so I can’t tell them to unenroll it. All that I have been able to do so far is sign in, using an account and password that was for some reason taped on the front (by the way, even this was difficult. the wifi refused to cooperate for a while). If anyone has any idea how I can get Linux on here, or atleast unenroll, please let me know.

Model: Acer Chromebook 13 (CB5-311, C810)
Board: nyan_big

Hi there

nyan_big is not only ancient, but also ARM (Nvidia Tegra)

You’ll probably never see any other OS on this

Oh. Alright. Is there any way I can unenroll though? Crostini is still perfectly fine (although I know the performance would be awful)

PostmarketOS currenly has “edge” versions in testing. Seems a good amount works but Display and 3D Acceleration might have problems?

You could also try this guy’s way of installing Linux on that Chromebook - imagebuilder/systems/chromebook_nyan/ at main · hexdump0815/imagebuilder · GitHub. It also has a lot of known issues and workarounds that may be useful to you even if you don’t use that project.

It won’t let me boot into it. It says “This device does not contain ChromeOS”.

What do you mean by “it” did you try installing Linux and booting into Linux doesn’t work?

I used the ChromeOS Recovery Menu by pressing ESC + REFRESH + POWER and it said “This device does not contain ChromeOS”. (It’s referring to the USB stick, which contained Velvet)
