Windows 10: Error installing update 20H2 for Windows 10 Pro. Error code: 0x8007042B - 0x4001E

I tried to install this update for Windows 10 and I see a screen that says install 95%, for about 5 minutes before the machine boots, it shows a screen of "Undoing the software installation", then rebooting to my old Windows. After logging in, I see the Windows 10 Settings dialog that says: We couldn't install Windows 10 We have reconfigured your PC to the way it was just before you started installing Windows 10.

Anniversary update fail. Error 0x8007042B - 0x4001E

I have been attempting to upgrade windows 10 pro, from version 10240 to version 1607 (anniversary update). I have tried both the Windows 10 Upgrade Assistant and the media creation tool (ISO). I get to 96% and, boom, every time it resets and restores my system to where it was before the upgrade started. The error I get is as follows:

0x8007042B - 0x4001E
The installation failed in the SECOND_BOOT phase with an error during PRE_OOBE operation.

I have searched for an answer and haven't found one. I have tried to trouble shoot it as best I can by unplugging everything but my keyboard/mouse, updated chipset, etc.. MS techs haven't been much help. Any thoughts? The iso is not on the OS drive, not sure if that matter. I would rather not have to nuke the system. I hate having to reinstall programs (adobe is the worst). Any help is appreciated.

Thanks.

 

Error code 0x8007042B - 0x4000D

Hi, I'd need your help.

I've tried to upgrade my current Win 7 Pro-version into Win 10 Pro-version, but the error code appeared in the final stage of the installing every time:

Error code 0x8007042B - 0x4000D
The installation failed in the stage SECOND_BOOT because the error took place during the function MIGRATE_DATA

In the control panel, Windows Update-section has been called as error code 0x8007042B - 2000D and there weren't any solution for this error in the guidelines .

I ran the sfc /scannow in the cmd and there weren't any defragmentations.

How could I get this error code fixed ?

My goal is to preserve all my music making plugins & files as they are in Win 7, so I'd like to keep some of my old files (Program files/Vstplugins, Program files (x86)/Vstplugins etc.) from Win7 to Win 10.

 

BIOS error codes

So I have motherboard with installed small LED screen, which presents BIOS error codes.

Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

Ex after installing sound card, the motherboard startup fails with the code 15.

Example picture of code is here.
