WARNING: you cannot go back to Chrome OS. This permanently installs Ubuntu!

Note: The 16.04 does not work! Only 14.04 works! 16.04 seems to work but will eventually boot into emergency mode and there is as of right now no fix! If you have any guaranteed fixes then please let me know!

UPDATE:All Ubuntu versions work except ubuntu mate

Now some people would install crouton and boot into Ubuntu there. But installing crouton DOES NOT INSTALL UBUNTU all it does is boot into Ubuntu while giving you access to chrome OS. If you decide that you don't want Chrome OS anymore than here are the steps

Things you will need:

  1. A spare computer (one without Chrome OS)

  2. 2 usb drives (at least one has to have more than 2GB worth of available space)


  1. This will wipe your local data, so make sure to back anything up that you don't have stored in the cloud. To put your Chromebook in Developer Mode:

    Press and hold the Esc and Refresh keys together, then press the Power button (while still holding the other two keys). This will reboot your Chromebook into Recovery Mode. As soon as you see Recovery Mode pop up—the screen with the yellow exclamation point—press Ctrl+D. This will bring up a prompt asking if you want to turn on Developer Mode. Press Enter to continue, then give it some time. It'll pop up with a new screen for a few moments, then reboot and go through the process of enabling Developer Mode. This may take a little while (about 15 minutes or so), and will wipe your local information. When it's done, it will return to the screen with the red exclamation point. Leave it alone until it reboots into Chrome OS.

    (Note that some older Chromebooks have a physical switch that you'll have to flip in order to turn on Developer Mode. If you aren't sure, look up instructions for your specific device on enabling Developer Mode.)

  2. Set it up normally, then press Ctrl-T to open the crosh. Type shell then cd; rm -f flash_chromebook_rom.sh; curl -O https://johnlewis.ie/flash_chromebook_rom.sh; sudo -E bash flash_chromebook_rom.sh then install option 1 (Have no fear as this option can't brick your system and safely installs a sea BIOS)

  3. Reboot your system. If it boots into a sea BIOS then good job! If it boots into Chrome OS you did something wrong. For the people who got it to work turn off your chromebook. Now go to your second PC and on the second USB install Ubuntu 14.04 on it, so you can usb boot it. If you don't know how to do this then follow the guide here.

  4. Go back to your Chromebook with your new bootable usb, and plug it in. Turn on the chromebook and press esc when given the option and select your USB. This will boot into an Ubuntu installation screen (This may take up to 30 mins, so be patient).

  5. Install Ubuntu normally and select erase other OS and install Ubuntu (Dual booting doesn't work with this method)

    Side note: If your keyboard doesn't work then reboot your chromebook and instead of installing it normally, click try Ubuntu. the keyboard should work, so click the desktop shortcut for installing Ubuntu, and now your keyboard should work! :)

  • To whoever added a snide remark and suggested it as an edit: I PUT THIS METHOD HERE BECAUSE MY CHROMEBOOK HAS NO WRITE PROTECTION SCREW -Love Hershel – Hershey Gamer Nov 26 '17 at 17:50
  • The url you provide returns a 404 error. Also, alt - T opened the crosh for me, not ctrl + T. Any way to find that script now? – David Nathan Sep 17 '18 at 8:34
