I have just purchased a chromebook, Asus C300, in hopes that I would be able to install ubuntu on it instead of chrome os. The other options I see are chrubuntu and crouton but neither really give me what I want as I don't have any need for chrome os and would rather free up the disk space.

So right now I have a 32bit copy of 14.04 on a flashdrive (I did it correctly via a windows machine). I turned OS verification off on my chromebook and entered it into developer mode which took a few minutes. But when I do recovery mode (escape + f3 + power) it says that the usb device does not contain chrome os. SO I'm doing something wrong but I don't know what. Any advice on how to proceed further would be greatly appreciated

To enable dev mode, you enter recovery mode (Escape + F3 + power key); this will trigger a screen with the message "Chrome OS is missing or damaged. Please insert recovery USB stick".

One this screen (the recovery screen), press ctrl + d - and follow the on-screen instructions.

Remember, this will wipe the device, and the Google disclaimer is: "Caution: Modifications you make to the system are not supported by Google, may cause hardware, software or security issues and may void warranty."

I was able to do it, you have to first remove the read/write screw from the motherboard. Warning this voids your warranty. As seen in the link bellow.


After that is removed I installed SeaBIOS https://johnlewis.ie/baytrail-release/

After that just have a Bootable Ubuntu Flash Drive ready and just go ahead and install. WARNING!!!! This worked for me but there is a risk of killing you computer every time you mess with the firmware of your computer. Also there is no turning back after installing the SeaBIOS.

Hope this Helps!


According to https://wiki.archlinux.org/index.php/Chromebook the C300 doesn't support legacy bios booting which to me appears that it cannot boot from a custom flash drive.
