This article will go how to troubleshoot if you're trying to reset a Chrome device (i.e. Asus Chromebit, Chromebox, etc.) and are seeing a "Chrome OS is missing or damaged. Please insert a recovery USB stick or SD card" error".
Please read the following before beginning
Recovering your Chromebit or Chromebox:
When your Chrome device operating system (OS) isn’t working properly and you’re seeing this error message: "Chrome OS is missing or damaged", you can recover it. Recovery is removing and reinstalling the OS. Note: If you’re using a managed Chrome device, you can refer to your administrator for help. They will be the most immediate and direct contact to assist.
What you need to get started:
- The Chrome device with the "Chrome OS is missing or damaged" error
- Another computer; a Windows or Mac computer with Chrome installed
- A USB flash drive that can hold at least 4 GB, and that you don't mind erasing.
Please Note: Recovery permanently erases everything on your Chromebit's and Chromeboxes’ storage
