What is the difference between System Recovery and Factory Reset in HP Recovery Manager?

System Recovery reinstalls the original operating system and then configures the settings for the programs that were installed at the factory. Factory Reset restores the computer to its original factory state by deleting all information from the hard drive, re-creating the partitions, and then reinstalling the operating system and factory-installed software. The HP Recovery partition (select products only) allows System Recovery only. (Page 10)
