Today it was my turn to have the Creator Upgrade forced on me
The download started and after some time the computer rebooted
Blank screen with blinking underscore like an old Dos box
Nothing no activity from HDD Zilch
Contacted MS support by telephone lots of apologies but no useful suggestions
I suggested that all indications were no OS was found after the post
We agreed that it was probably a corrupt or missing MBR
After one and a half hours I was informed that M.S could do nothing and their recommendation was Download and install windows 10 again and lose everything
My computer would not boot no internet access how could I download?
I suggested that I could boot to LINUX from a usb distro or use Hirams to work on the MBR and back up my HDD to an external storage drive as I did not want to lose everything They would not even acknowledge that this could work
Microsoft Tech is not helpful Be warned!
To close my tale some good news
I prepared the laptop to receive Linux etc and to be on the safe side I removed the sd picture card from the card reader and then rebooted
EUREKA it booted back to Windows upgrade and everything is now installed and upgraded.
The computer was trying to boot from the sd card!!!!
Perhaps the tech people need to stop jumping to conclusions and revise their basic check list
Yes folks check your BIOS settings and make sure HDD is first boot device when upgrading
