Attention: If you need updated device drivers, do not download them from the Windows Update Web site. Obtain them from Lenovo. For more information, see “Making sure device drivers are current” on page 132.

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 “Creating and using a rescue medium” on page 62.

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 “Creating and using a recovery media” on page 59.

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 program. For details on how to temporarily or permanently change the startup device sequence, see “Startup menu” on page 126.

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.
