Before installing Ubuntu on your Chromebook, you first need to enable Developer Mode.
Enable Developer Mode
While most of your data in Chrome OS is stored server-side in the cloud, you may have important files saved locally, such as those found in your Downloads folder. In addition to disabling certain security restrictions and allowing you to install a customized version of Ubuntu, activating Developer Mode deletes all local data on a Chromebook automatically. Therefore, back up essential local data on an external device or move it to the cloud before taking the steps below.

The main reasons to choose Crouton are its simplicity, and it can run Chrome OS and Ubuntu side-by-side, eliminating the need to hard boot into one operating system at a time. To get started, open the Chrome browser, and follow these steps:

The version of Ubuntu that you installed doesn’t come with much pre-installed software. The most common method for locating and installing Linux applications is through apt-get. This command-line tool searches for and downloads countless applications within Ubuntu. AMD and Intel-based Chromebooks offer access to more working applications than those running ARM chips. However, ARM-based Chromebooks run some of the most popular Linux applications.

While most data and settings in Chrome OS are automatically stored in the cloud, the same cannot be said for files created or downloaded during your Ubuntu sessions. Use Crouton to back up your Ubuntu data.
