Recovery overview 63 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.
