Solving recovery problems

of the following:
• Use a rescue medium to start the OneKey Recovery Pro workspace.
• 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 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
