Chapter 5. Troubleshooting
When do I need to restore the system to the factory status?
You can use this feature when your system fails or you need to re-install your operating
system. This will restore your computer back to the initial status when you first booted up
your computer after receiving it from the store. If there is critical data on your current
partition, back it up before you run this recovery feature.
