Creating and using a recovery USB drive
You can create a recovery USB drive as a backup for the Windows recovery programs. With the recovery
USB drive, you can troubleshoot and fix the problems even if the preinstalled Windows recovery programs
are damaged.
It is recommended that you create a recovery USB drive as early as possible. If you did not create a recovery
USB drive as a precautionary measure, you can contact Lenovo Customer Support Center and purchase one
from Lenovo. For a list of the Lenovo Support phone numbers for your country or region, go to:
