Failed Windows 7 to Windows 10 Upgrade

After dozens of successful upgrades, one of the last machines is causing me issues.   The upgrade from Media Creation Tool appeared to be progressing normally.   When Windows 10 finally came online there was a popup box notifying me that the computer could not be upgraded, however I was presented with a Windows 10 login screen.   When I entered the username/password the screen went blank with only the cursor arrow.   I have tried logging in as both the domain user and the local admin user but without success.   I was eventually able to boot into Safe Mode with the intent of rolling back to Windows 7.   However, I cannot get into "Settings" as when I right click the start menu and select "Settings" nothing happens.   I attempted to start Settings by running ms-settings: but get "This service cannot be started in Safe Mode".   The Start menu does not even work.

I have tried running sfc /scannow but it finds no integrity violations.    I have attempted a startup repair from a Win 10 boot CD but it also could not find any problems.

Is there an alternative way to revert to Windows 7 besides going into Settings?

Restart the system then as soon as you see the Windows logo, hit ctrl-alt-delete three times, on the forth it should go into Windows repair
Much depends on what you are after in terms was this system upgraded to win10 when offered for FreeBSD was rolled back?

This deals if you want to try to reset it to gave win10 reinstalled.

Alternatively reboot, let it go the login screen, but instead of logging in, while holding the shift key, select the power restart option
Try to get into the system using safe mode, and try to trigger the rollback to 7.

Hi,

Have you try create another local account using safe mode?
Can you login to the windows account without using safe mode?

Thank you for all of the helpful recommendations.    Unfortunately, I tried each one but was unable to resolve the issue.    I eventually was able to roll back to Windows 7.   As I mentioned previously I could login through safe mode, but was unable to get into settings, search etc...    I was however able to run msconfig.    From there I setup a clean boot which was successful and gave me full control of settings.    (Obviously there was a conflict with a program and/or service preventing Win 10 from starting.)    From within settings I was able to recover my original Windows 7.    The machine is too old to waste any more time finding the conflicting program/service so it is a perfect excuse to replace it.
