Performing a System Recovery on Your HP Chromebook (Chrome OS)
This document applies to HP Chromebook computers with Chrome OS.
If you see the error message Chrome OS is missing or damaged , or if there is another serious problem with your Chromebook, it may be necessary to reinstall the Chrome operating system.
Performing a recovery on your HP Chromebook reinstalls the operating system and restores the original factory settings, removing all associated Google Accounts (including the owner) and clearing all local data from the hard drive. Locally saved files and saved networks are deleted for all accounts. The Google Accounts themselves, and any data synced to the Web through your Google Drive, are not affected by a system recovery.
This document describes how to create recovery media, and how to use the recovery media to restore your Chromebook to its original condition. Follow the steps in this document to perform a system recovery on your Chromebook.
Before you begin a Chromebook recovery
Before beginning the Chromebook recovery process, you need the following:
- A USB flash drive or SD memory card : You need 4 GB or greater capacity on your storage device to accommodate the recovery image. All data is erased from the device when creating the recovery media, so back up any files from the device before you begin.
- Access to another computer : To create the recovery media, use a Windows, Mac, Linux, or Chrome OS computer on which you have administrative rights and Internet access.
- Chromebook power supply : The Chromebook must be plugged into a power source during recovery.
- Chrome OS is missing or damaged screen : If this message is not already displaying on your Chromebook, trigger the screen manually. With the Chromebook turned on, hold down the Esc + F3 (Reload) keys, and press the Power button. The Chromebook restarts, and the screen shows Chrome OS is missing or damaged .
Step 1: Finding your Chromebook hardware model name
There are numerous variations of HP Chromebook hardware. In order to create the correct recovery media for your specific device, you must select the recovery image that matches your exact Chromebook model.

If your Chromebook is displaying the Chrome OS is missing or damaged message, find the model name at the bottom of the screen.
