OneKey Rescue System

Introduction
The Lenovo OneKey Rescue System is an easy-to-use application that can be used to back up
the data on your system partition (C drive) for easy restore when required. You can run Lenovo
OneKey Rescue under a Windows operating system, and the OneKey Rescue System without
starting the Windows operating system.
Attention:
• In order to utilize the features of the OneKey Rescue System, your hard disk already includes a
hidden partition by default to store a system image file and OneKey Rescue System program
files. This default partition is hidden for security reasons and is the reason the available disk
space is less than it claims. The exact available hard disk space depends on the file size of the
mirror image file (based on the size of operating system and pre-installed software).
• You can use the Restore to factory default feature to restore the system partition (C drive)
back to the factory default, i.e., the state your computer was when you purchased it. Make
sure you back up any critical data stored on the system partition (C drive) to other media,
such as another disk partition, CD/DVD discs or removable storage devices.
Using Lenovo OneKey Recovery in Windows
In Windows, you can create a backup of an entire system partition, saving it on your local hard
disk. You can back up your data to a CD, DVD, or other removable disk. In addition, you can
also create Windows recovery disc(s) to boot and recover your system.
Notes:
• The backup process and creating recovery disc may take some time, connect the AC adapter and battery
pack to your computer.
• After the recovery discs are burned, please number them so that you can use them in the correct order.
• For computers without an optical drive, an external optical drive is needed to back up or to create a
recovery disc.
For more instructions, see the help file of Lenovo OneKey Recovery.
Using Lenovo OneKey Recovery System without the main Windows operating
system
In the event that the operating system cannot be loaded, you need to recover your system with
the OneKey Rescue System, which includes several applications to help you detect and remove
viruses, and recover Windows system and data. Pressing the OneKey Rescue System key
activate Lenovo OneKey Rescue System when your PC is turned off. Within the program, you
can restore your system partition to the original factory status, or to a previously generated
backup. You may also transfer critical data or documents to other storage devices. All these
features make OneKey Rescue System an important utility for securing your data.
Note: It is not recoverable if Restore to factory default or Restore from backup has been run. Make sure to
back up any critical data before you run these features.
