I think you are stuck in a startup repair loop as described in this Microsoft Windows document.
First run diagnostics to make sure there's no bad hardware like the disk or memory.
Have you run diagnostics?
| Tap the ESC key after powering on. Tap it once a second after you see the LEDs on the keyboard flash. When you see the startup menu, press F2 to run diagnostics. If a component fails during the UEFI test then Click here to check warranty and Click here for world-wide contact info |
Since Windows cannot start then you need to enter Windows safe mode from outside of Windows
Hold down the shift key and turn the power on. If windows does not start in safe mode then read this article about safe mode. Skip down to 'Enter safe mode from outside windows. If F11 does not get you into system recovery then try turning the power on and off three or more times in a row.
Since the startup repair fails then do the restore point.
This video describes how to use a restore point.
If there are no restore points or the restore point is so far back that you'll lose a lot of programs then you need to bring up the device manager and see if you can fix the problem.
Find the device that has the error icon and try to fix it.
===if you cannot get into safe mode====
1 - see if you have cloud recovery
Go to the below site and enter your product ID including the 3 characters after the # character
If you have cloud recovery you can restore your system using a 32gb flash.
It may take an hour or more to create the recovery USB.
