Reinstall ChromeOS

How can I reinstall Chrome OS?

There are a few different methods to reload Chrome OS. Below are examples and reasons for using each method:

Reset your Chromebook with Powerwash

Powerwashing can solve most issues.
Powerwashing does not require a USB flash drive or file download.
Use a Powerwash if there is a bug with your user profile or owner permissions.

Wipe device data

Similar to a Powerwash
Use this option for devices that are enrolled on a work or school network.

Restore your Chromebook with a USB flash drive or SD card recovery media

Reload with a USB flash drive if other recovery options have failed.
Restore with a flash drive if you get the message "Chrome OS is missing or damaged."
Use this option if the currently installed OS is corrupt or has a bug (ex. it has difficulty updating).
