® Recovery Pro

„Recovery media and rescue medium
Recovery media is used to restore the hard disk drive to the factory default 
settings. Rescue medium is used to recover the computer from failures that 
prevent you from gaining access to the OneKey Recovery Pro workspace on 
your hard disk drive. 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.
„Performing backup operations
The OneKey Recovery Pro program enables you to back up all your hard 
disk drive contents including the operating system, data files, software 
programs, and personal settings. You can designate where the OneKey 
Recovery Pro program stores the backup.
Notes:
If your computer is preinstalled with a GNU/Linux operating system, recovery system is 
not available.
To utilize the features of the recovery system, your hard disk already includes a hidden 
partition by default to store the system image file and the recovery system program files. 
This default partition is hidden for security reasons, which explains why the available 
disk space is less than the stated capacity.
The recovery process is irreversible. Make sure to back up any data you wish to save on 
the system partition before starting the recovery process.
The recovery process may take a while. So be sure to connect the AC power adapter to 
your computer during the recovery process.
