No problem with the SSD as it was not mounted, sorry you have lost track but I was trying to install 1709 on the HDD with the DVD player in the slot I now use for the HDD. The addition of the SSD has only been since, NOT DURING and fits in the DVD slot of my LAPTOP
MY LAPTOP NOW HAS 1709 LOADED AS CLEAN INSTALL, NO USB DEVICES AND DRIVERS RELATING AND NO SSD!
I now have the mammoth job of reinstalling everything, some 90 pieces of software (not counting Microsoft V C++ etc) and setting them up as needed. Then there are all the drivers to check to see if they are the latest for the DELL components. It will take me a month or more of my free time.
MEANWHILE I AM STILL USING 1703 WITH ALL UPDATES STOPPED. Microsoft should have taken on this problem rather than my being left in the ****. Yes, you have tried to help but after 5 tries by Windows Help Desk I would have thought someone may just be sufficiently awake to recognise that there is something wrong with the approach by Help Desk to the problem. If sfc and dism are inadequate does Microsoft not have anything better to diagnose the problem!
