Just to clarify, a System Restore
, is performed within Windows and only replaces system files and settings from a previous time/date. It does not influence data files such as My Documents, My Music, or photos. I don't believe that this is what you are requesting information about.
A System Recovery
, per your video link and what I summize you are talking about, will overwrite the hard drive, including any of your documents, music, and photos. It will return your computer to the state it was in when you first purchased it. Before performing a system recovery, you should copy all important files to alternative media (i.e. a different hard drive (not the drive being recovered)
or CD and DVD discs).
It looks as if the HP recovery process gives you the option to back up files before the actual recovery ( writing over your hard drive) takes place. My advice to you is backup your files before you attempt the recovery
. Why? Because you have more time to search your drive to make sure that all important files are backed up. You are not under pressure to decide in 30 seconds what needs to be saved.
I hope this helps.
