Attention: If you need updated device drivers for your computer, 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 86.
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 114.
• Use recovery media if all other methods of recovery have failed and you need to restore the hard disk drive
or hybrid drive to the factory default settings. See “Creating and using a recovery media” on page 111.
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 or
hybrid 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 detailed information on how to temporarily
or permanently change the startup device sequence, see “Startup menu” on page 79.
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.
