How to Download ChromeOS Flex

There are two methods for downloading ChromeOS Flex: the trial method and the direct ISO BIN file download. Note that when you work with a certified Google partner such as Promevo, they can assist you through the downloading process and ensure your devices and data are secure when you download ChromeOS Flex.

Method 1: The Trial Method

ChromeOS Flex allows live boot by running the OS directly from your USB device without installing it. The live boot option preserves your device’s data and OS, so you can test ChromeOS Flex before installing.

Note that Google recommends you fully install ChromeOS Flex instead of using live boot because live booting has performance and storage limitations and doesn’t support automatic updates or enrollment for management.

To perform the trial method, get the device you booted using the USB installer:

  1. On the Welcome to ChromeOS Flex screen, click “Get started.”
  2. On the Start Using ChromeOS Flex screen, click “Try it first.”
  3. Follow the on-screen instructions.
  4. Sign in to the device.

Method 2: Direct ISO BIN File Download

If you want to install ChromeOS Flex from an ISO or BIN file, you can do so in a few simple steps:

  1. Create the USB installer. The device you use to create your installer can differ from the device you plan to install ChromeOS Flex on. The installer is where you will download ISO files.
  2. Then, install Chromebook Recovery Utility by opening the Chrome browser, going to the Chrome web store, and at the top right, click “Add to Chrome.” Then, when prompted, click “Add extension.” 
  3. Once the Chrome Recovery Utility is installed, launch the Chrome Recovery Utility extension in the Chrome browser. Then, click “Get started,” click “Select a model from a list,” and for “Select a manufacturer,” find and click “Google  ChromeOS Flex.” For “Select a product,” find and click “ChromeOS Flex,” and click “Continue.” 
  4. You’ll be prompted to insert your USB drive and click “Create now.” When you get a message that your recovery media is ready, remove your USB drive from the device.

How to Install ChromeOS Flex

  1. Turn off the device you want to run ChromeOS Flex on.
  2. Insert the ChromeOS Flex USB installer into your USB port.
  3. Boot the device from the USB drive by pressing the power button and repeatedly pressing your boot key.
  4. Select your USB installer as the boot device using:

    2. BIOS or UEFI Menu - If your interrupt triggers a BIOS of UEFI menu, you’ll need to find settings related to Boot or Startup. Then follow the instructions to set your USB installer as the first, primary, or preferred boot device.
    3. Other Menu - If you see other options on the screen, navigate to an option that matches one of the above mentioned menus, then follow the steps listed.
