Hi AO,
As reported before, everything I did to reduce the possible source of the problem failed same as always at 45% first boot.
I have opened a new partition on the HDD and installed 1709 onto that with nil problems using the latest 1709 .iso on DVD from startup for that purpose. For some reason my SSD, located in what was the optical drive bay, continued to be recognised
as USB upon boot so I was unable to use a usb memory card for that purpose ( yes, I had to remove the SSD to allow me to remount the DVD player and reboot twice to get the fact recognised)
I would have preferred to have loaded the 1709 version to the SSD but when I put the SSD into the laptop HDD slot I had startup problem as the drive was not recognised. Rather than solve another problem I took the easy way because it will not
take long to clone the 1709 onto my SSD where it will be much, much, faster for me to swap versions during rebuilding the 1709 OS to my needs and the existing for my work needs. I suppose that using a virtual version would be easier and even faster but I
have not managed to find the time yet to play with virtualisation of Windows, I know I should but all my spare time and a lot of my work time has gone into getting 1709 to load along with a VLAN problem at my local BT exchange (UK) causing frequent internet
disconnections which they have finally located but cannot fix for the next 3 weeks.
I have a list of drivers for the un-updatable 1703, I will do a comparison check for differences between newly installed 1709 plus when I finish reloading all my software to see if anything stands out regarding size version and date etc. If anything
obvious appears I will let you know.
