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 86. • 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 82. 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 Setup Utility program. See "Startup menu" on page 140 for detailed information about temporarily or permanently changing the startup device sequence. For more information about the Setup Utility program, see "BIOS Setup Utility" on page 138. 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. Chapter 5. Recovery overview 87

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 86.
•
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 82.
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 Setup Utility program. See “Startup menu” on page 140 for detailed information
about temporarily or permanently changing the startup device sequence. For more information about the
Setup Utility program, see “BIOS Setup Utility” on page 138.
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.
