Windows 10: Upgrade from pre-installed 1903 to 20H2 48% Black Screen and crash.

I had the above problem when upgrading my new ASUS Zenbook Duo from pre-installed version 1903 to 20H2 (BSOD and auto-restored the previous system). Tried everything in similar 48% crash posts on this site, but nothing worked. Then as a last resort, I turned off "Bitlocker" (I did not know it was turned on by default by the manufacturer) and a black screen at 48%, and then, after about 5 minutes of black (and a small prayer) VOILA... It continued at 85% and installed!!!!

I do not know if this will help others but it may be worth a try.

Windows 10 Pro 1803 Upgrade to 1903 Black Screen at 48%

Hi, Thanks for your reply.

I have done most of the steps as mentioned in your post.
I have removed all the USB devices, left only the MB, Display Card, SSD (C drive) and Data Drive (D drive).
1) chkdsk c: /scan - normal no bad sector.
2) SFC /scannow





3) BIOS - latest as per in Asus website.
4) C drive free space is about 110GB
5) setuperr.log and CBS.log as attached, setupact.log is about 150MB and not able to attach here.

It happens to Bluescreen appeared after i have left the PC on for about 15 mins after the black screen appear. it shows DRIVER_PNP_WATCHDOG failure. Not sure is PNP referring to the plug and play display card as I only left this card in the PC system.




Thinking to trying 1809 version but unable to find it in MS website.

 

Windows 10 Pro 1803 Upgrade to 1903 Black Screen at 48%

The black screen at 48% is normal and happened to me also as I upgraded. It just takes some time for the update process to complete. The black screen will go away on it's own as the update completes. How much time it takes is up to the hardware in your computer. My black screen lasted about 5 to 6 minutes.

 

Windows 10 Pro 1803 Upgrade to 1903 Black Screen at 48%

I have recently trying to upgrade my windows 10 pro from 1803 to 1903 due to end support in Nov 19 message given by MS.
I have tried all the upgrade method and all given the same result.
1) Upgrade from windows update and setting.
2) ISO file - with the drivers, etc. updates uncheck. only keep my files and programs.
3) Media create tools etc.
The upgrade will complete windows 10 installation, but when come to restart for updating, it reaches 30% and restart again, and continues the upgrade, when reaches 48%, the upgrade blue screen will become black screen and stop there.
