Attention: Using OneKey Recovery will result in loss of data.

• You can restore the C: drive of the computer to factory default settings or to the last system backup status using OneKey Recovery. If you do this, all of the existing data on drive C: will be lost, but the content and format of the other partitions of the hard disk drive will remain unchanged.

• If you want to install an operating system and back it up with OneKey Recovery, you must format the C: partition in NTFS format and install the operating system on the C: partition. Otherwise, the OneKey Recovery system cannot run.
