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 fail ure. You can also create user backups 
for easy restoration as required.
• If your computer is preinstalled with a GNU/Linux operating system, OneKey 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.

used to restore the system partition.  To back up the system partition:
1In 
Windows, press the Novo button or double-click OneKey Recovery
