@brejoc you can install Linux ‘inside’ chrome os - not great for EOL. Or install a dual boot Linux, Ubuntu works but Gallium is tuned for chromebooks https://galliumos.org/. There are a lot of steps, this is good overview: https://itsfoss.com/install-linux-chromebook/. Use chrome browser on Mac/win to download usb chromeos recovery, there is a browser xtension for it
@brejoc only problem I had was I dual boot and gallium updated the boot loader and default option set wrong partition. Part name wasn’t clear so maybe take notes when installing.
