Please post the make and model of this computer. I will find instructions for using the recovery partition.
Most of these partitions revert the computer to the condition it had when it came out of the box. This means that any programs, pictures, videos, data, etc. will be lost when you use the recovery partition.
Having said that, I will add that some manufacturers have a second option which will not effect your data. I won't know if this is an option for you until you post the requested information.
