If you are lucky the original recovery partition is still intact see the tutorial here:
If the HP recovery does not work you would have to get your hands on a Windows 7 Home Premium 64 bit OEM disk or a copy of the HP restore disk set for your computer. HP no longer offers it but you can perhaps get it from 3rd party vendors.
What upgrades had you thought about doing?
