Windows 10: Windows 10 upgrade 1909 to 2004 failed with error 0x8007042b - 0x4000D

Hi,


I've been trying to upgrade my Windows 10 installation 1909 to 2004, and having tried a lot of things without success It always rolls back the upgrade with the following error message:

Error 0x8007042b - 0x4000D The installation failed in the SECOND_BOOT phase with an error during MIGRATE_DATA operation

windows update for 1909 works properly and I get updated as needed. In my attempts to perform the upgrade I've been trying everything I could including:

1. run DISM and SFC commands to fix corruptions there aren't any
2. remove softwaredistribution folder
3. remove Avast AV
4. perform clean boot
5. perform upgrade from media creation tool

I really need some help to investigate the log files to determine the root cause as reinstalling without apps will be extremely painful in my case. I've prepared the following files and can share directly with any advisor who will be willing to take a look if more are needed I can provide:

• Setupact.log and Setuperr.log from the following path C:\$Windows.~BT\Sources\Panther
• Setupact.log and Setuperr.log from the following path C:\$Windows.~BT\Sources\Rollback

Windows 10 upgrade - Error 0x8007042b

Hello,

As with many users, I'm encountering the same issue when trying to upgrade my PC to 1909 from 1803. I used the Windows 10 Media Creation tool to create an ISO and mount it virtually, then executing the update. I've disabled all external antiviruses, and
even use the Malwarebytes Removal tool to scrub Malwarebytes from my system. I've ran sfc /scannow and DSIM online image repair in safe mode. The update still continues to fail. Any help would be much appreciated.

This is the thread I followed to try to read the logs, but I really don't know what to look for:

Win 10 Anniv fail - 0x8007042B - 0x4000D AND rasadhlp.dll


just started to research this...

0x8007042B - 0x4000D failed in the second boot phase with an error in the migrate_data option

the worst part is, the restore messed up my computer ... have an error with windows\system32\rasadhlp.dll file and the online help doesn't repair it.

should i try to get the update to work and hope that fixes the dll problem?

i'm gonna do a clean boot and reinstall it and see if that works.

... and it worked. I forgot the clean boot upgrade/update trick til I saw it... I had to do it to upgrade from 7 to 10.
