Impossible. There is noticeable disk i/o up to that point and then if you do not select the windows repair on the "windows error recovery" it will boot after counting down a timer. In most cases it will boot to the repair. So there would be a lot of disk i/o and it would be clearly visible on that HD light. You also said you had it up for an hour so it would have kept doing disk i/o. I work on that model all the time and that model almost always has windows 7 loaded (unless they downgraded for some reason which I doubt) so thats how it would work.
Look, you made a mistake on diagnosis, we all do it sometimes, but I was only trying to tell you that when you ask for help you have to be more specific with what you see. If you were listening for disk i/o why would you not also be looking at the light on the front which is impossible to miss.
If you would have said "I only see the backlight come on and then there is alot of disk drive light flashing" I can tell you a dozen techs here would have told you the first thing to do is hook up an external monitor.
