Is this your only HD or did you already unplug one? If so plug it back in and take another snap to post back. I'm wondering why there are no flags on what should be the OS partition. Have you done anything to it at all?
CLick on HD in PW to highlight it, from Disk tab select REbuild MBR, Apply. Does it start now?
If not try running Startup Repair 3 separate times with reboots the way it is.
