Want to install Ubuntu on Chromebook [duplicate]

The real version of Ubuntu on Chromebook is called Chrubuntu.

I have done this, and even got it working great, but after a few months it wouldn't boot. There's no way I can tell you how to do it in one post. Go for it, but remember it's imperfect. Here's the most important resource:

However, I'm going to say that you shouldn't do this. It's a hassle (think 8 hours of setup time), when another distro now supports Chromebooks out of the box. You can use pendrive linux's universal installer to install the Chromebook flavor of Bodhi linux, and you'll find yourself probably much more at ease

Make sure you get the chromebook flavor: http://bodhilinux.com Of course you still have to configure the Chromebook itself to allow it: http://jeffhoogland.blogspot.com/2014/01/howto-bodhi-linux-on-acer-c720.html
