Windows Boot stuck at loading ambakdrv.sys

Introduction:

You may encounter a problem of loading driver ambakdrv.sys when you boot the Window from the cloned disk or from a new disk on which a system or disk backup image is restored.

The problem might be because there is a conflict between ambakdrv.sys (a driver of AOMEI Backupper)and other drivers of the program.
