From my experience, a Chromebook is so locked down to protect your account, it's not worth trying to boot another Linux version onto it. You can run a Linux image inside its VM, although the performance is a bit poor:
- Install Penguin on the machine (Linux) with 100gb
sudo apt update
- Install quickemu https://github.com/quickemu-project/quickemu (download the .deb file)
- Mint worked best for me:
quickget linuxmint 22 cinnamon
- Edit the conf file to increase the disk space to 30-40gb, higher resolution
- Follow the terminal output instructions for running it, e.g.
quickemu --vm ...
- On Mint itself, you likely have to download deb files for Chrome, Visual Studio Code.
