By now everyone must have tried out the Virtualized version of Chrome/Chromium OS in either VirtualBox or VMWare. But to the the real feel of the OS, which is the Speed, you need to prepare a bootable USB that can plug into any PC/Mac and will run lightning fast.
Tip: If you are totally new to chrome OS: What is Chrome OS – Everything you need to know.
If you have tried Virtualized version and doubted the speed, you must give the USB version a try:
Here’s how to Write the Image on the USB:
Unzip using WinRar, Download Image Writer and launch it, select the image (chromiumos.img) and your USB drive letter from the drop down box. Click “Write”. The install image will then be copied to the drive. Once it’s done, close the program and you can then boot from the USB drive.
Firstly, unmount the drive you want to install Chromium OS to. Place the downloaded file onto your desktop. Open System Profiler, click USB on the list at the side and then select the entry that represents your USB disk. Now look for the BSD Name column (http://bit.ly/5mG4WK). Remember what is written here. In my case, it is disk1, but in yours it may be different. Take care here as if you get it wrong, it could seriously mess things up. Once you have this, open up Terminal and
type the following commands.
tar -zxvf chromiumos.tar.gz
For the next command, replace X with the name of the disk you found earlier, ie disk1.
sudo dd if=chromiumos.img of=/dev/X bs=4m
This command will ask you to enter your password (the same one you enter when installing
software for example), type it in and press enter. This command will take a while to run,
about 20 minutes for me, and then will give you your shell prompt back once it has finished.
Once it has, you can remove your USB drive and boot from it (but not on your Mac because
I’ll tell you now that won’t work, yes I tried it)
If It says “Resource Busy“!, You forgot to dismount the drive. Do this, then retype the command and you should be fine.
Extract chromiumos.img and run the following command in the same directory as the file, where X is the device name of your USB drive.
sudo dd if=chromiumos.img of=/dev/X bs=4M
Once the command finishes, you can then boot from the USB drive.
