What happens if I deprovision a device?

If you use the Google Admin Console to deprovision devices, those devices no longer apply the policies and features that you set in the Admin console. To start managing devices again, you’ll need to re-enroll them after powerwashing or re-installing ChromeOS Flex. For information about deprovisioning devices, go to Repair, repurpose, or retire ChromeOS devices.

Can I install ChromeOS Flex on a ChromeOS device that has reached its AUE date?

Each Chromebook, Chromebase, and Chromebox has an Auto Update Expiration (AUE) date. On and after the AUE date, devices no longer receive software updates from Google.

Google does not support installing ChromeOS Flex on a ChromeOS device that has reached its AUE date.

While you might be able to install ChromeOS Flex on Intel or AMD x86 ChromeOS devices, we don’t support devices that have reached their AUE date. You might have issues with firmware and hardware compatibility, installation, and updates.

How do I create a ChromeOS Flex USB installer on Linux?

To create a USB installer on Linux:

  1. Download the installation image from CrOS Updates Serving. In the Codename column, look for reven.
  2. Extract the zip.
  3. Insert your USB drive. Be sure to remove all other removable media.
  4. Open a terminal or command line.
  5. Use the command to write the image to USB:
    sudo dd if=image_name.bin of=/dev/sdN bs=4M status=progress
    • image_name.bin—The name of the extracted installer file
    • /dev/sdN—The USB drive

Can I uninstall ChromeOS Flex?
When you install ChromeOS Flex on your device, all existing data that is currently on the device is erased and permanently unrecoverable.

Google does not provide steps for how to uninstall ChromeOS Flex. Instead, you can install a different OS on your device using instructions provided by the device OEM or another OS provider. Typically, installing a different OS removes ChromeOS Flex from the device.

Why can't I use Windows to format my ChromeOS Flex USB installer?

When you‘ve finished using your USB device as a ChromeOS Flex installer, you might want to wipe it and use it for storage again. We recommend that you use Chromebook Recovery Utility to format your ChromeOS Flex installer. If you use the default Windows method, the device’s storage capacity might appear to shrink because Windows does not recognize all ChromeOS Flex partitions.

For instructions on how to format your USB drive using Chromebook Recovery Utility, see Format your USB drive.

Why is storage limited when I live-boot ChromeOS Flex?

While you can live boot ChromeOS Flex from the USB installer, Google recommends that you fully install it on devices. When you live-boot ChromeOS Flex, limited storage is available because of the layout of ChromeOS Flex's partition table.

ChromeOS Flex is a relatively large OS compared to common linux distributions. To make sure that you can use USB drives from as many manufacturers as possible to create your ChromeOS Flex installer, we reduce the size of the installer image, which limits storage space. For the moment, this is not a feature that can be changed.

To avoid keeping files on the limited live-boot USB drive, consider using a second USB drive, SD card, or Google Drive to store them.

Live booting is only recommended for temporary exploration or testing. We strongly recommend full installation for the best ChromeOS Flex experience.

What happens to my existing files and OS when I install ChromeOS Flex?

When you install ChromeOS Flex on a device, it completely erases all data—including all programs, settings, and files that were previously saved. Be sure to back up all important files before you install ChromeOS Flex. Files erased during installation are not recoverable.

Can I use a CD-ROM, DVD-ROM, or floppy disk drive with ChromeOS Flex

In general, CD-ROM, DVD-ROM, and floppy disk drives do not work with ChromeOS Flex.

Can I use USB Wi-Fi dongles with ChromeOS Flex?

ChromeOS Flex officially certifies only whole-models as configured from OEMs. We don’t support peripherals, including Wi-fi dongles, but they often work.

Why do I need Chrome Enterprise Upgrade or Chrome Education Upgrade?

Before you can enroll ChromeOS Flex devices in your organization, you need to purchase a Chrome Enterprise Upgrade or Chrome Education Upgrade for each device you want to manage. Then, you can use your Google Admin console to manage devices, apply policies, and get support.
