Ok, I tried “refreshing” windows using option one and it worked. I followed the instructions and had no problems. However, the system did not ask me to insert my usb flash drive. So far so good, and this morning I checked for updates and found and installed successfully the latest cumulative update KB3147458. Should I install manually all the earlier cumulative updates that were missed? Now, I have to re-install all the apps that were removed.
Thanks to you, "firebooter" and the rest of the GtG members that at one point tried to help me.
