Yes, I first scanned with Windows Defender. Rebooted. Then selected scan with Windows Defender Offline and the machine rebooted as it should, but did not complete, but hung with a black screen with intermittent activity of the hard drive. I was finally
able to get it to proceed by constantly entering my key pad code and right clicking with the mouse while it was rebooting. I suspect the screen for sign in did not appear and thus it would not proceed without sign in. Don't really know; just a guess.
