Windows 10: Windows 10 is stuck on logon screen please help

Hello there
My laptop has stopped working !
It is stuck on the login screen it's running on Windows 10 . I already removed the SSD and put it into an USB case and run a virus check ,but it's still got that message*Sad .
Please check the pic here:




I tried everything it just won't work anymore.
What can I do I already tried to revenue windows with a USB stick but it failed at 90percent saying " It can't be installed.."
I'm so desperate*Sad.
Has somebody experienced the same and can help me now ?
I need this laptop for school.
Best regards
Kevin

Can you get to the Troubleshoot options and use Automatic Repair or System Restore ? Press power button down until totally off. Then turn On as SOON as you see the screen light up. Repeat twice and your Advanced Options should appear. Looks like this -

I did but it does not repair,it just tells me that it can't be installed or repaired.
Is there a special DVD from Windows or so to fix error's?I used the normal win 10image

 

If you have access to a 2nd computer, download and create a Macrium boot disc which has a boot repair option. There's a full tool guide at the beginning of the tute.
