Installing

This page covers the basics of installing GalliumOS from a USB flash drive or an SD card, using the traditional ISO method. If you want to use chrx to dualboot GalliumOS with ChromeOS, see GalliumOS on chrx

Installing from USB or SD media allows you to use your entire SSD or HDD for GalliumOS. You can also use GalliumOS Live to try out the features of GalliumOS before you even install it!

1. Go to Preparing for GalliumOS and get your Chromebook ready to run GalliumOS.
2. Download a GalliumOS ISO from the downloads page on GalliumOS.org
3. Write (or "burn") the ISO to a USB flash drive or an SD card. Detailed instructions for this are at Making GalliumOS Bootable Media
4. Plug your USB flash drive or SD card into your Chromebook
5. Reboot your Chromebook and boot from the USB flash drive or SD card.
   1. If you have custom firmware, press Esc at the BIOS screen and press 2 to boot from USB.
   2. If you have the scary white screen, press Ctrl+L.
6. Wait for GalliumOS to boot up. Once in the live environment you can play around with GalliumOS, or you can install it using the Install GalliumOS icon on the desktop.
