Before I began fooling around with another computer, I would, go to services, by typing services in the startup search. In services go to windows installer. Go to recovery tab. Follow instructions for setting up recovery actions for your computer. This one should work. My policy is always try the easiest step first.
Using the other computer is a bit more difficult. But now I am sure we can get you up and going soon. I have to leave for a while. Post any problems or questions. Someone will be here to help. I will check as soon as I return.
