The Chrome OS has a Developer Mode that gives you root access to the operating system of your Chromebook.

Therefore, back up all important files before you enable the developer mode. To enable developer mode on a Chromebook running Chrome OS, follow these steps: Turn off your Chromebook.

If you're a developer, you also can put your Chromebook into Developer Mode, to install applications, and get deeper access to the ChromeOS system.

First, Developer Mode enables you to run alternative operating systems, which means that you can install Linux or other operating systems alongside Chrome OS.
