Solving recovery problems

Note: Ensure that your rescue device is set as the first boot device in the startup device sequence in
the Setup Utility program. See "Selecting a startup device" on page 38 for detailed information about
temporarily or permanently changing the startup device sequence. For more information about the Setup
Utility program, see "Using the Setup Utility program" on page 35.
If you cannot 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 68.
• Use recovery media if all other methods of recovery have failed and you must restore the hard disk drive
to the factory-default settings. See "Creating and using recovery media" on page 65.
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.
