Service causing the problem
If you have installed a Software or a Driver after which you were not able to start Windows in Normal or Safe mode then this should possibly be because of a service loaded by the Software or the driver that is causing the problem.
Note: You may disable any other application/driver service too from the recovery console to fix the problem.
