Chapter 3. Lenovo OneKey Recovery system
The Lenovo OneKey Recovery system is software designed to back up and 
restore your computer. You can use it to restore the system partition to its 
original status in case of a system failure. You can also create user backups 
for easy restoration as required.
„Backing up the system partition
You can back up the system partition to an image file. This image file can be 
used to restore the system partition. To back up the system partition:
1In Windows, press the Novo button or double-click OneKey Recovery 
icon to start the Lenovo OneKey Recovery system.
2Click System Backup.
3Select a back-up location and click Next to start the backup.
„Restoring
You can choose to restore the system partition to its original status or to a 
previously created back-up point. To restore the system partition:

icon to start the Lenovo OneKey Recovery system.
2Click System Recovery. The computer will restart to the recovery environment.
Notes:

Recovery system is not available.
To utilize the features of the OneKey Recovery system, your hard disk already includes a 
hidden partition by default to store the system image file and the OneKey Recovery 
system program files. This default partition is hidden for security reasons, which explains 
why the available disk space is less than the stated capacity.
Notes:
You can choose a back-up location on the local hard disk drive or an external storage device.
Remove the removable hard disk drive before starting the Lenovo OneKey Recovery 
system. Otherwise, data from the removable hard disk drive might be lost.
The back-up process may take a while.
The back-up process is only available when Windows can be started normally.
