Solving recovery problems

If you are unable to access the Rescue and Recovery workspace or the Windows environment, do one of the following:

•Use a rescue medium to start the Rescue and Recovery workspace. See “Using a rescue medium” on page 116.

•Use recovery media if all other methods of recovery have failed and you need to restore the hard disk drive to the factory default settings. See “Using recovery media” on page 112.

Note: If you are unable to access the Rescue and Recovery workspace or the Windows environment from a rescue medium or recovery media, you might not have the rescue device (an internal hard disk drive, a disc, a USB hard disk drive, or other external devices) set as the first boot device in the startup device sequence. You must first make sure that your rescue device is set as the first boot device in the startup device sequence in the ThinkPad Setup. See “Startup menu” on page 204 for detailed information about temporarily or permanently changing the startup device sequence. For more information about the ThinkPad Setup, see “ThinkPad Setup” on page 201.

It is important to create a rescue medium and a set of recovery media as early as possible and store them in a safe place for future use.
