Creating the USB drive 

The first thing you must do is create the bootable USB flash drive. Download the correct image for your device on your Linux machine (keeping in mind the proper chipset), to the ~/Downloads directory, and follow these steps: 

  1. Open up a terminal window
  2. Change into the Downloads directory with the command cd ~/Downloads
  3. Rename the downloaded file to galliumos.iso
  4. Plug in your USB drive
  5. Download UNetbootin and burn the iso to the flash drive
  6. Allow the process to complete.

You can now remove the USB drive and plug it into your Chromebook. 

First things first

Before you install GalliumOS, I highly recommend creating a recovery USB flash drive. Chromebook offers a simple solution for this. Just follow these steps:

  1. Boot up your Chromebook and login
  2. Plug in a spare ~2GB+ USB flash drive
  3. Open the Chrome browser
  4. Go to chrome://imageburner
  5. Follow the simple instructions.

When all is said and done, you'll have a recovery drive to use to get your system back where it was (should you not like either Linux install or something goes wrong).

Now, it's time to start the process.

�Boot into Developer mode�

The next step is to reboot your device in developer mode. This is done by holding down the Escape and Refresh button and then tapping the Power button. When the device reboots, you will be greeted by a screen with a warning. Tap CTRL+D to continue on. You now have access to the developer mode and can enable the necessary boot flags. Here’s what you need to do:

  1. Press CTRL+Alt+T
  2. In the bash screen, type shell and hit Enter
  3. Enable to necessary flags with the command sudo crossystem dev_boot_usb=1 dev_boot_legacy=1

�Boot into Live Session

You can now insert your USB drive and reboot your Chromebook. When you are presented with the same warning screen as earlier, hit CTRL+L and the device will boot from the USB drive.
