This page covers the basics of installing GalliumOS. There are two basic ways to do this. You can install from a USB flash drive or SD card, which will allow you to use your whole SSD or HDD for GalliumOS, along with other more complicated configurations, such as dualbooting with Windows or other Linux distributions. You can also use chrx, which is a user friendly script written by User:reynhout that will allow you to dualboot GalliumOS and ChromeOS on the same computer with relative ease.
