You upgraded a device driver, and windows immediately failed and restarted. the problem is that it seems to be in a continuous restarting loop. what boot startup option will restart normally and give you an opportunity to try to troubleshoot the problem after a normal reboot?

The answer is safe mode.

Explanation:

Safe mode is a boot option used by many operating systems which can be used as a diagnostic tool. It runs the system by only allowing the essential software to start; this way, it's possible to find the source of the problem, and fix it or delete it so that the system starts working again.

In this instance it would be especially useful, because it disables all devices except those required for input.
