well this totally killed my install. Downloaded set to upgradefrom 10122 reboot loop. Installed 10074 clean would not set up a user correctly so installed 9926 installed fine this would not update so updated it to 10074 again installed fine. Downloaded the 10130 update created a stand alone usb installer rebooted. The update crashed as before so tried to boot from the usb and this displayed the same reboot loop.

Will try with a different SSD later but very strange
