Chromium OS is the open-source equivalent of Chrome OS. In fact, the latter is derived from Chromium OS, and then Google adds its proprietary apps, including Gmail, Google Maps, Play Store, and more. If you don’t have a Chromebook yet, but would like to try features of Chrome OS, then test driving Chromium OS is an excellent way to start. You can install it on a USB flash drive and boot directly into it without affecting your current PC configuration.

Installing Chromium OS on a USB flash drive

You can create a Chromium OS USB flash drive on a Linux, Windows, or macOS system.

Requirements

• A USB flash drive with at least 8GB capacity
• Windows, Linux, or macOS PC

Process

Step 1) Plugin the USB flash drive to your computer.

Step 2) Download the latest Chromium OS image from the below link. You should notice several versions there. It includes ARM and 64-bit processor versions. Windows, Linux, and macOS users should download the Camd64OS-XXX.img.7z version, where XXX is the date of the build. As you see, they maintain daily builds.

Step 3) After the download is complete, extract the content of the 7zip file. If you couldn’t decompress the archive, you should install 7zip. After successful decompression, you should see an IMG file.

Step 4) For burning the IMG file to the USB flash drive, we shall use a free application ‘BalenaEtcher.’ It works on Windows, Linux, and macOS, but just make sure you download the correct version for your PC.

Step 5) Launch Etcher.

Step 6) Etcher should automatically detect the USB flash drive.  Click on “Select Image” and then browse and select the extracted Chrome OS IMG.

Step 7) Click “Flash!” and wait for the flashing process to finish.

Step 8) After the flashing is complete, close all the programs and shutdown the PC. You can leave the USB flash drive plugged-in as we will be using the same PC to test the new Chromium OS USB drive.

Step 9) We shall now boot your PC into the USB drive. Typically, Windows machines let you choose the boot drive when you press the F12 key during startup. macOS users need to press and hold the option key during the boot. Below is an example of a Windows/Linux based PC.

Step 10) Your PC should boot into Chromium OS.

Enjoy!
