Windows 7 stuck at boot screen, Safe Mode boot with System Restore ineffective

I recently went through a Windows Update (Sunday, December 16th), and my computer applied the updates and shut down. Upon restarting it, my computer (Sony Vaio VGN-NW270F) kept getting stuck at the boot screen. I tried to do Last Good Configuration, but that didn't get me past the boot screen. Safe Mode will let me in, but no matter how far back I go with System Restore, it still won't boot up. I don't have a recovery disk (though I know I could make one), but I'm not sure what to do if System Repair won't work and System Restore doesn't help.
