HI PCR,
Out of all the permutations I used it is a problem to get straight exactly what the sequence was. Yes, I installed 1709 on the HDD but in the end I did a Clean Install on the SSD of 1709, there is just too much history to repeat as the between steps.
1709 was installed on the 0 drive which was the SSD and the original Win 10 1703 (and 1709 from which the clone below originated) in that location moved to the Optical Drive location . I had cloned 1709 to the SSD but despite modifying the registry it was still recognised as a usb drive for GKW reason, I certainly do not. To cure this problem I changed the partition size and formatted the drive and installed Win 10 Pro 1709 SAVING NOTHING.
The more you dig around this I am sure the more confused you will become as I have enough problem keeping trace of the convolutions: All that matters is that my current 1709 version on the SSD in the 0 Drive location is a Clean Install to that drive in that location as I have repeatedly stated.
