Automatic repair loop

[Kinowa]

When I boot my laptop it shows diagnosing pc then proceeds to blue screen which says "PC did not start correctly". I already tested my hard drives by shutting my laptop down then spamming ESC then pressing f2, all of it passed so it's not a harddisk problem.

That's because this is a KNOWN issue and it is unrelated to hardware.

Unfortunately, that nearly always means that a recent Windows Update failed and Microsoft then tried to recover from that, but that failed, so it's trying over and over again -- and will never succeed because Windows Update got corrupted in the process.

These problems were reported with KB4532693 back in February of 2020, and more recently, with KB4556799. Unfortunately, this is NOT a new issue with Win10 Windows Updates.

First thing you need to do is see if you can restart in Safe mode -- by doing these steps: https://www.tenforums.com/tutorials/2304-boot-into-safe-mode-windows-10-a.html

If you don't know how to start using Advanced Startup Options, then read this: https://www.tenforums.com/tutorials/2294-boot-advanced-startup-options-windows-10-a.html

Then, follow these steps to reset Windows Update: https://www.tenforums.com/tutorials/24742-reset-windows-update-windows-10-a.html

If these work, when you finally reboot, you should then be able to login to a working Windows desktop.

I can't boot to safe mode, when I click f4 or 4 to boot in safe mood it just repeats the problem pc repairing/ diagnosing pc, then returns to a blue screen with "your pc did not start correctly" what should I do?
