(cid:132) 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 Recovery under the 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 the 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).

(cid:132) Using Lenovo OneKey Recovery (within Windows operating system) In Windows operating system, double click the OneKey Recovery system Icon on the desktop to launch Lenovo OneKey Recovery. Within the program, you can back up the system partition on the hard disk drive, other storage devices, or by creating recovery discs. Note:

(cid:129) The backup process and creation of recovery discs may take some time, connect the AC adapter and battery pack to your computer.

(cid:129) After the recovery discs are burned, please number them so that you can use them in the correct order.

(cid:129) Computers without an integrated optical drive support the creation of recovery discs;

however an appropriate external optical drive is needed to physically create the recovery discs. For more instructions, see the Help file of Lenovo OneKey Recovery. 25 Chapter 4. OneKey Rescue system

(cid:132) Using Lenovo OneKey Rescue system (without Windows operating system) In the event that the operating system cannot be loaded, follow the steps below to start OneKey Rescue system.

(cid:129) Shut down your computer.

(cid:129) Press the OneKey Rescue system button to start OneKey Rescue system. Within the program, you can choose to restore your system partition to the original factory status, or to a previously generated backup. Note:

(cid:129) The recovery process is irreversible. Make sure to back up any critical data before using the recovery feature.

(cid:129) You can use the tip of an unfolded paper clip (or similar object without a sharp tip) to gently press the OneKey Rescue system button.

(cid:132) Creating a recovery disc(s) 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):

(cid:129) Insert a recordable disc into the optical drive on your computer. Note: 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.

(cid:129) In Windows, press the OneKey Rescue system button to launch Lenovo OneKey Recovery system. 26 Chapter 4. OneKey Rescue system

(cid:129) On the main screen, click Create Recovery Disc.

(cid:129) 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.

(cid:129) Insert additional recordable disc(s) when prompted. Note:

(cid:129) The estimated number of discs needed will be displayed before the process of creating the recovery disc(s) begins. To minimize the number of discs needed, use recordable DVDs as the media. Also make sure your optical drive is compatible with the disc intended for use.

(cid:129) After recovery disc creation, number the discs appropriately for use in their correct order. The first disc created will be used to start the computer in the case of a system failure. 27 Chapter 5.
