Solution below: Cause: I set my laptop Windows 10 to start in DIAGNOSTIC MODE using msconfig (I use my laptop with wireless internet) On boot I was presented with the windows start-screen and was unable to get to the log-in-screen Clicking the start-screen did nothing, pressing SHIFT and power button changed the display to show my name. Solution: I plugged in an ethernet cable to connect my laptop to the internet and the log-in screen appeared. (Luckily I had an ethernet to USB cable!) Alternative solution: Use a bootable thumb drive with windows 10 and reinstall windows or go back to a restore point. Suggest everyone makes a provision for this sort of eventuality. ENABLE SYSTEM RESTORE AND ENABLE THE F8 BOOT MENU OPTION To enable the start-up boot menu option on pressing F8 do this.... OPEN command prompt as administrator and type: bcdedit /set {current} bootmenupolicy Legacy note, to undo above command (bcdedit /set {current} bootmenupolicyStandard) =========Alternative========== bcdedit /set {bootmgr} displaybootmenu yes bcdedit /set {bootmgr} displaybootmenu no Now you can get to the old boot menu as windows starts Hope this helps someone
