I ask for the OS as one proceeds differently depending on the OS that you're using.
Can you access Startup Repair? Here's a link about it: http://pcsupport.about.com/od/toolsofthetrade/ss/windows-7-startup-repair.htm
If you can't access Startup Repair, there's not much else to do with Windows 7.
Beyond that, the first thing to do is to backup your data. You can do this several different ways (if the data is still present and accessible on the hard drive).
Once the data is backed up, then try these free, bootable hardware diagnostics: http://www.carrona.org/initdiag.html
OR, you can use the built in hardware diagnostics if your HP has them (and if you can access them from the boot menu by tapping the Esc key as the system boots).
Then, if the diagnostics pass, you can reinstall Windows 7 by using F11 to access the recovery partition (this works for most HP's)
If the recovery partition is damaged (or the hard drive diagnostics fail the hard drive), then you'll have to use recovery disks.
If you don't have them, you can order them from HP (link is for HP owners in the US: http://www.carrona.org/recdisc.html#hp )
