How to Fix the 'Chrome OS Is Missing or Damaged' Error on Chromebooks

Try these steps in order until your Chromebook can boot successfully:

  1. Power the Chromebook off and on. Press and hold the Power button until the device turns off, then wait a few seconds and press the Power button again to turn it back on.

  2. Powerwash (reset) the Chromebook to factory settings. If you're able to log in to the Chromebook, powerwash Chrome OS to return the machine to its original state.

    Performing a factory reset erases your locally stored files, so make sure you back up everything to your Google Drive.

  3. Recover Chrome OS. If the computer is still stuck at the Chrome OS is missing or damaged screen, then your only option is to perform a fresh install of the operating system. You can find instructions on how to do that below.

    Reinstalling Chrome OS in recovery mode completely wipes the hard drive, including your downloads and personal files.

  1. Using the Google Chrome browser on a working computer, download and install the Chromebook Recovery Utility by selecting Add to Chrome in the Chrome Web Store.

  2. Launch the program. You're asked to provide the Chromebook model number, which you can enter manually or choose from a list.

    If prompted to grant the OS permission to make changes to the USB drive or SD card, select Yes or Allow

  3. Plug in your USB flash drive or SD card, and then follow the on-screen prompts to download Chrome OS to your removable media.

  4. Once the download is complete, remove the USB drive or SD card.

  5. With the Chromebook powered on, hold Esc+Refresh on the keyboard, then press the Power button to reboot in recovery mode.
