Your computer does not ship with a recovery disc. You can use Lenovo 
OneKey Recovery system to create a recovery disc(s), which can be used to 
start and restore your computer in case of a system failure.
To create a recovery disc(s):
• Insert a recordable disc into the optical drive on your computer.

• In Windows, press the Novo button to start Lenovo OneKey Recovery 

system.

• On the main screen, click Create Recovery Disc.
• Choose the type of recovery disc(s). You can create three types of recovery 

disc(s): recovery disc(s) with existing backup image, recovery disc(s) from 
the current system partition, and factory default recovery disc(s). Select the 
type of recovery disc you want to create and follow the on-screen 
instructions.

The recovery process is irreversible. Make sure to back up any critical data before 
using the recovery feature.

If your computer does not come with an integrated optical drive or if the integrated 

optical drive does not support disc creating, connect an appropriate external optical 
drive to your computer.
