Installing Linux on Your Chromebook
Crostini, Chrome OS' official Linux project, is supported by all Chromebooks released since 2019, however it also works on certain older computers.
On the official website, you can see if your gadget supports Linux.
Google has Linux turned off by default, so you'll have to turn it on manually and install it.
To access the "Settings" menu, click the gear symbol on the notification panel.
Turn on the "Linux development environment" under Advanced > Developers On the next window, click "Install.".
Choose a username and the size of the Linux partition. You have the choice of using the "Recommended" option or customising it (depending on the intended use for the Linux installation.)
