Download and extract the 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.
Q: How big a USB drive does this require?
A: The brand new Diet version requires only a 1GB USB drive, compared to the 4GB the old version required. Magic, eh?
Q: What are the default username/passwords for this build?
A: Default username is facepunch, default password is facepunch.
Q: Help, I can’t get past the login screen because of a network error!
A: Simply login with the details above and try and get your internet working, reboot and the settings will be remembered, allowing you to login with your Google Account as normal.
Q: I tried formatting my USB drive after trying this out and it’s smaller than it was! What gives?
A: You need to repartition your USB drive. Use the appropriate tool on your OS to create one large partition in place of the three small ones. (Windows: Disk Management, Mac: Disk Utility, Linux: fdisk)
Q: Help, it doesn’t boot!
A: Firstly, check your file downloaded properly. Then, try re-imaging the image onto the USB drive and booting from it again. Try another USB drive if you can, and if it still doesn’t work, it’s your laptop that isn’t compatible in all likelihood.
Q: WiFi/some other component isn’t working, can you help?
Q: It runs really slowly, isn’t this supposed to be super fast?
A: Sadly not, the hardware support in ChromiumOS is really quite limited, but manufacturers are hard at working adding the changes needed to get it running smoothly. Try a new build as I post them and you may find it’s working much better.
Q: Can I install this to my HDD/SSD?
A: You sure can, but please be warned it will overwrite everything on the drive. I’m also not sure if this will work on those hybrid storage models. Press Control-Alt-T whilst logged in on the USB version, and then type /usr/sbin/chromeos-install and follow the prompts. Reboot to your HDD and you should have it installed.
Q: Why’s it called Diet?
A: Because it now fits in only 1GB of space! So you can now use a 1GB USB drive or SD card, and there’s just about no downside. I also added more wireless support.
