Important.Notes
In order to utilize the features of OneKey Recovery, your hard
disk already includes a hidden partition by default to store a
system mirror image file and OneKey Recovery program files.
This default partition is hidden for security reasons and is the
reason the available disk space is less than it claims. The exact
available hard disk space depends on the file size of the mirror
image file (based on the size of operating system and pre-
installed software.)
You can use Restore to Factory Default feature to restore the
system partition (C drive) back to the factory default, i.e. the
state your computer was when you purchased it. However,
once you restore to this status, you will not be able to restore
the system to another previously backed up state. Therefore,
make sure you back up your critical data on the system
partition (C drive) to other media, such as a another disk
partition, CD/DVD discs or removable storage devices. 1.
