Reloading IdeaCentre B300 to factory default


I used this B300 Ideacentre desktop for quite a while and realised that it has slowed down a bit , so I would like to do a reformation to it . But the question is how do I do it ? A complete reinstall so that nothing will remain in my computer , no current data or anything .



The OneKey Recovery application can be used to complete wipe your system and reload it to factory state.  Please note that all user data will be lost in the process and depending on the age of the system, you may need to then reinstall Windows and other driver updates from the Lenovo support site to bring your system up to the latest level.


The following is excerpted from Page 28 of the system users guide...


OneKey Recovery is an easy-to use application. You can use it to restore your
computer to the system default or a previously backed up state.

Detailed Operation Procedure:

1. Turn on the computer. When the Lenovo logo appears, press the F2 key on the
keyboard to start the Rescue System, then you can select OneKey Recovery.
Note: System Recovery will overwrite all of the data on drive C. To prevent
loss of data, be sure to back up relevant data before performing system

2. Follow the onscreen instructions to select the backup task you want to restore
from and disk you want to install operation system, and press Next to start

3. Please wait during the process of system recovery. Do not interrupt the
operation during the recovery process.

4. After the system is recovered successfully, the software prompts to restart the
computer. Restart the computer and enter the system.

I've tried this as I'm getting "repairing disk error, this may take an hour to complete". This did not work now just have a black screen, now have my screen saver...nothing else will not advance past icon page. Any other advice that I could try?
