No login prompt in minimal boot 'safe mode" - windows 10

[Windows Central Question]

With the latest windows 10 update, something went awry with my outlook and I read to launch minimal mode on boot to troubleshoot. Ahhhhh!! On boot, it just stopped at the startup picture - with no login prompt. All I can do is restart. Tried shift key option. No effect. Navigator and magnifier showed no promise either. Everything was just fine on my system, except outlook.
