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 Startup ➙ 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.
