Install Chromium OS on USB Flash Drive with Ubuntu/Linux Mint

This article is for those who want to install and run ChromiumOS onto a USB storage device. Let us see how it can be done with the OS image.

Open the terminal and run these commands to download the ChromiumOS image to your home folder:

mkdir ~/ChromiumOS; cd ~/ChromiumOS
wget -c http://goo.gl/ICSpt -O ChromeOS-Vanilla-3274.0.zip
unzip ChromeOS*.zip
mv ChromeOS*.img ChromeOS.img

Run the following commands and to identify the USB device:

fdisk -l

If you mounted the USB flash drive as /dev/sdb1 on your system.  Use the command and unmount the USB device:

sudo umount /dev/sdb1

Use your USB device name and replace /dev/sdb1
Run the following command to create a bootable USB device with the Chrome OS image. It will delete all data from your USB device.

sudo dd if=ChromeOS.img of=/dev/sdb1 bs=4M

sudo dd if=ChromeOS.img of=/dev/sdb1 oflag=direct

Boot from the Chromium OS USB flash drive after finishing the process. To boot from USB storage devices, you can use the Plop boot loader too. the ChromiumOS VM can download and use from http://goo.gl/G0ZSk when you fail to create a bootable USB stick.
