Creating bootable GalliumOS media is very similar to other Linux distributions. Unfortunately, that doesn't mean it's easy. The goal of this guide is to make it as straightforward as possible.
Contents
On Linux
First, you need to download the GalliumOS iso for your Chromebook.
Once the iso is finished downloading (you MUST wait for it to finish), open up your favourite Terminal emulator.
cd to the place where you downloaded the iso. It's probably ~/Downloads.
cd ~/Downloads
Plug in your USB device, identify it, and unmount it. This is a little tricky. You can use lsblk to get a list of storage devices attatched to your system. Try to find out which one is your USB flash drive. It is very important to not get this wrong, as it could cause catastrophic data loss. Once you've figured it out, make sure the USB flash drive is unmounted.
sudo umount -f /dev/sdb1
Be sure to replace sdb1 with the actual partition name as listed in lsblk. Next, use dd to copy the ISO to the USB flash drive.
dd bs=1M if=galliumos.iso of=/dev/sdb
Be sure to replace galliumos.iso with the filename of the iso you want to write. Usually typing "galliumos" and hitting tab will autocomplete it for you. Also be sure to replace sdb with the actual device as listed in lsblk. Make sure to write to the DEVICE and NOT the partition. This process can take a long time depending on the speed of your flash drive, USB connection, and hard drive. Be patient. Once the prompt comes back, the ISO should be written. If you're getting errors, try adding sudo to the beginning of the command. Before you unplug your flash drive, be sure to run sync
On Mac OS X
- Download the GalliumOS ISO for your ChromeOS device: https://galliumos.org/download.html
- Insert USB media into Mac OS X machine
- Carefully determine device path for newly inserted USB media from a Terminal.app windowbash$ diskutil listThe device path will be something like
/dev/diskN. ReplaceNin all steps below with the correct disk number.⚡It is extremely important to determine the correct device path for your USB media in this step. Using the wrong device path in the following steps could damage your OS X install and cause irreparable data loss! - Unmount USB media from OS Xbash$ diskutil unmountDisk /dev/diskN
- Copy the ISO to USB mediabash$ sudo dd if=./galliumos.iso of=/dev/rdiskN bs=1m★Be sure to use the
rdiskdevice name in the output file (of=parameter), and use the correct path and filename for thegalliumos.isofile which you downloaded in step 1. - Eject USB media from OS Xbash$ diskutil eject /dev/diskN
- Remove USB media from Mac OS X machine, it's now ready for your ChromeOS device
On Windows
Windows is a little tricky. I will write a few guides once I have access to a Windows box.
On ChromeOS
ChromeOS is very similar to Linux, but noy identical. I will write a proper guide as soon as I have access to a Chromebook (that I haven't installed GalliumOS on :P)
