Enable Developer mode on Chromebook

Posted by

Are you looking to install Linux on your Chromebook or Windows 10? If so, the first thing that you will need to do is enable developer mode on your Chromebook. Also, these instructions could differ depending on your Chromebook model. For this tutorial, I am going to be using the Acer C720.

Enable Developer Mode on Chromebook:

*This process will erase everything on your Chromebook. So backup anything that you might need.*

Enabling Developer Mode:

Make sure your Chromebook is on and logged into your account. Now you will need to reboot into recovery. To do this, while holding down the ESC + Refresh Button, tap the Power button.

You should be rebooted into the recovery. You will see the text, “Chrome OS is missing or damaged.” Don’t worry, nothing is actually missing or damaged.

Next, hit CRTL + D to turn off OS verification, then press Enter to confirm. Your Chromebook will reboot and begin to factory reset your device. It will reboot again once it’s done.

From now on, when you reboot your Chromebook you will get the recovery screen that says OS Verification is off. You can either wait 30 seconds, to hit CRTL + D, to boot right into Chrome OS.

Enable USB Booting

If you want to install another operating system such as Android or Windows on your Chromebook, then you will need to enable USB booting. To do it, it’s very easy.

On the Chrome Login screen your four account, type in CRTL + ALT + F2 (forward arrow) to bring up the console window. For the login, type in chronos.

Then type in the following:

sudo bash

crossystem dev_boot_usb=1 dev_boot_legacy=1

sudo reboot

Now, when the OS verification screen comes up you can hit CRTL + L  to bring up the legacy bios and boot devices.

That’s it. If you have any questions or comments feel free to leave them below.
