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.
Notes:

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.
