Installing Linux on the Acer Chromebook R11

Posted on 2018-10-23

Requirements

Acer Chromebook R11
Internet connection
Flash drive
Screwdriver

1. Enable Developer Mode

Power off the chromebook.
Press esc + Refresh + Power to boot into Recovery Mode. The chromebook will boot to a white screen that says "ChromeOS is damaged or missing".
Press Ctrl+D to enable Developer Mode, then follow confirmation steps.
The chromebook will reboot to a white screen that says "OS verification is OFF". This is Developer Mode.

2. Disable Write-Protect Mode

Power off the chromebook.
Unscrew the back cover and remove the write-protect screw, then screw the cover back on.

3. Flash Firmware

Power on the chromebook, sign in or browse as guest, then press Ctrl+Alt+T to enter crosh. Type "shell" and hit Enter.
Enter the following command and choose option 3.

cd; curl -LO https://mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh

4. Download GalliumOS

Enter the following command to download GalliumOS:

curl -o galliumos.iso https://galliumos.org/releases/3.1/galliumos-3.1-braswell.iso

Plug in your flash drive and identify it using "lsblk". It is *very important* to get this right.
Unmount your flash drive with "sudo umount -fq /dev/sda", replacing "sda" with the name of your drive.
Write GalliumOS to the flash drive, replacing "sda" with the name of your drive:

sudo dd bs=1M if=galliumos.iso of=/dev/sda ; sync

Wait until writing is complete (it may take a while).

5. Install GalliumOS

Reboot with the flash drive inserted. GalliumOS should boot automatically.
Once GalliumOS boots to the desktop, click the "Install" icon.
Follow the instructions to set up the installation.

That's it.

You've successfully installed Linux on your Chromebook.
