• 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.
Note: If you are unable to access the OneKey Recovery Pro workspace or the Windows environment from a
rescue medium or recovery medium, 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 BIOS. Go to the Boot menu to temporarily or permanently change the startup device sequence.
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.
