How to create a bootable USB from Chrome OS

[sduverge]

So I made a huge mistake and deleted the linux image I was using (didn't do the uname -r check before).
I'm currently downloading 16.10 to upgrade via USB but I need to create the USB on my chromebook since the one I'm trying to fix lost internet access and can't mount any external drive. I do have another partition for /home so I'll try to fix boot before losing all hope and my files.
How do I make the bootable drive from my chromebook?

Ubuntu isos are hybrid which means that all you need to do is copy the image to the device using dd:


sudo dd if=image.iso of=/dev/theDevice

where image.iso is the name of the 16.10 image and theDevice is whatever the device is (e.g. sdb). N.B. Be careful that you don't choose the device from which your Chromebook boots.
