GalliumOS on chrx

This page covers the basics of using chrx to dualboot GalliumOS with ChromeOS. This will only work on Haswell Chromebooks out of box, and Broadwell Chromebooks with a small tweak. Sandy Bridge, Ivy Bridge, and Bay Trail Chromebooks are not supported.

Installing GalliumOS via chrx will allow you to run a dualboot, with GalliumOS and ChromeOS, allowing you to choose between them at boot.

Note that chrx only works with certain Chromebook models, so be sure to review the hardware compatibility list.

1. Follow the steps are Preparing for GalliumOS to make sure your Chromebook is ready to boot GalliumOS.
2. Boot up and log in to your Chromebook, and connect to the internet. Make sure you have a good stable internet connection.
3. Press Ctrl+Alt+T to open up a crosh session. Type shell and press enter to start bash.
4. Run chrx
   1. curl -O https://chrx.org/go && sh go -d galliumos
   2. You can add more options to the end to customize your install. See the chrx documentation for more information.
5. Follow on-screen instructions to repartition your SSD and install GalliumOS. Be patient, it may take quite a while depending on your internet connection and SSD speed.
6. When it's all done, reboot your Chromebook. Now you can press Ctrl+D at the scary white screen to boot to ChromeOS, or Ctrl+L to boot to GalliumOS.
