My computer won’t bootup, how do I do a recovery without losing data?

I have a Hewlett Packard media center computer and it has a problem booting up.. I heard there is a way to reinstall windows on the "factory image" partition and not lose all the data on my harddrives.. how do I find directions to do this? I have backup recovery disks (3 DVDs I burned), not a Vista installation disk.

Data Recovery?

My harddisk crashed few days ago due to which I lost my all data. Although after re-installation it is working but it has developed many bad sector and hence it may crash again. My concern is the recovery of data. Can anyone tell me about good data recovery software? particularly:
software which allows scan for specific portions of partition so that recovery process can be carried out in stages since it takes very long time to scan whole partition specially when there are bad sectors?
Also allow to choose specific files (by types, name, size etc) to search?
