HDD not detected after install

So, a few days ago I downloaded a host of updates over night and set the installer to work before leaving in the morning. It ran for about 12 hours before I checked it again and it appeared to have completed some, but was hung up on one update or another. I let it running another hour or so before killing it since it was really slowing down the PC.
When I restart the PC, it appears as if my primary HDD is no longer detected. I dont have a boot disk for the Windows 7 x64 that I am running, only an old Win XP that doesnt have a useful key. Is a fresh install my only option here?
