Can't log in to Windows or start up computer after upgrade/Ctrl Alt Del lock screen issue

[blynch3]

I upgraded to Windows 10 last night. It completed and I appeared to be logged in to Windows 10, but then it immediately asked me to restart again. I can't recall if the restart request had anything to do with Windows 10 or if it was a separate Windows update, but I allowed it to restart.

Upon restart, I see a lock screen telling me to "press CTRL ALT DELETE to unlock." (On this screen, I can see the wireless and battery icons in the right corner, but they can't be clicked. This is all I can see on the screen other than the CTRL ALT DEL prompt.) When I press CTRL ALT DEL, I get a spinning wheel for a few minutes, and then eventually it takes me right back to the same CTRL ALT DEL lock screen. Hard restarts do nothing. Taking the battery out does nothing. I can't get into safe mode at all.

I appreciate any help that can be provided!

Hello blynch3

Can you try getting to the Safe Mode externally, i.e. using the second method described in this tutorial?

Once in the Safe Mode, you can then try following the instructions given here to rectify the issue.

Let me know if this helped. Good Luck!!
