- On a Chromebook, Linux OS will work alongside Chrome OS, so you can switch between them at any time. To switch between Linux and Chrome, press Ctrl + alt = "Image" + Shift + Back arrow and Ctrl + alt = "Image" + Shift + Forward arrow Where Ctrl + alt = "Image" + Back arrow and Ctrl + alt = "Image" + Forward arrow, if you are using an Intel Chromebook.
- Create recovery media for your Chromebook before installing Linux in case you experience difficulty or software malfunction during the installation process. You can use the recovery media at any time to restore your Chromebook to its factory settings.
- Install the Linux programs on your Chromebook using the apt-get command in the terminal. For example, if you want to download Firefox for Linux, type sudo apt-get install firefox in the terminal to install the Firefox browser.
