Windows 10: Slow booting up - Windows stuck on black screen for several seconds

Hello everyone!
I'm facing a problem with my Asus S400C running Windows 10 (currently v. 20H2).

I'll describe the whole situation from the beggining.
Almost two years ago, I upgraded my notebook by installing a new SSD. I performed a clean installation of Windows 10 Home. Everything had been ultra-fast, untill some update ruined everything (march-may 2020). From that time, my laptop is booting up very slowly. After loading screen with Windows 10 logo, and before login screen, Windows is stuck at black screen with no cursor. That screen lasts for over 30 seconds.
What I have done so far:
- clean installation of Windows 10 (yesterday) - problem was solved maybe during first boot
- safe boot - no change
- disable all services except these from Microsoft and then restart - no change
- disable windows error reporting service - no change

ntbtlog shows that there are some drivers that are not loaded during boot:
BOOTLOG_NOT_LOADED \SystemRoot\System32\drivers\dxgkrnl.sys (several times)
BOOTLOG_NOT_LOADED \SystemRoot\System32\drivers\CAD.sys
BOOTLOG_NOT_LOADED \SystemRoot\System32\DRIVERS\NDProxy.sys (few times)
BOOTLOG_NOT_LOADED \SystemRoot\system32\drivers\wd\WdFilter.sys

Maybe my problem is somehow connected with these drivers?

I'm exhausted. My notebook is booting up longer than when I had HDD.

Any ideas?

:)

 

Black screen after 'Starting Windows' sequence

Sounds like the old... windows black screen of death.

Try this quoted from "VisiHow" article "Repair Windows 7 Black Screen of Death":

They, also, have some other options there, too.
Google search and you will find a lot of the "Windows Black Screen of Death with cursor" fixes.

 

windows 10 slow boot

I was having a slow boot issue on my Windows 7 install a little while back. It would take about 30 - 40 extra seconds to boot up for whatever reason.

I would try following these steps, while this didn't solve my issue, it did increase Read/Write to where it should be.

In the end, I had to reinstall my Windows 7 entirely to fix the booting issue. It was taking around 35 seconds to boot, and after the fresh install it takes about 7 seconds to boot.

I see that you are facing black screen issues with the system. This might be due to the corruption of display driver in the system.
