Gamer 007, I had exactly the same problem. I got to the end of the boot and everything stopped dead as soon as windows was due to load. I did several resets with exactly the same result. I got so mad I pulled the plug out of the wall. I came back 10 minutes later plugged in and started it up. Guess what it booted perfectly! There must have been a bug in the update, has microsoft made any announcements? dAVE.
Edit: Best Of Luck.
