[SOLVED] Need Help KB4592449 and the Feature update 20H2 fails to install

[robertkjr3d]

My computer components are the fastest of the fastest.
Processor: AMD Ryzen 9 3900X 12-Core Processor 3.8mhz
Board: X570 Aorus Ultra
Bios: American Megatrends F11 12/6/2019
Vid-Card: AMD Radeon RX 5600 XT
Bios Mode: UEFI
Ram: 64GB
Windows Drive is M-2, with an EFI partition...
The Windows build though is older and cloned from a previous build. So this is not a fresh install. I have no desire to rebuild.

SFC results: No integrity problems found.
DISM results: No component store corruption detected.

I've tried running SFCFix.exe immediately after KB4592449 fails and wakes from boot. It does:

Attempting repair . . .
Stage 1
Stage 2
Stage 3

But hangs after running DISM... Interestingly, even though visibly DISM runs successfully.

So in 'Update-History', the 20H2 Feature-Update fails with 0x80070003. And KB45922449 fails with 0x800F0922. Other updates like Defender, and driver updates have gone through.
I've tried the standard things like, stopping net-windows-update 'net stop bits'.... etc and then renaming the SoftwareDistributionFolder and CatRoot2 folders.
I've tried scanning the CBS.log myself.

Here is a link to the entire CBS directory zipped

My symptoms are identical to what happens to this user and what he put in his text. Unfortunately, he also did not receive a response.
He wrote:
"I launch the installation, everything seems to work fine, the pc requires to reboot, during reboot the updates reaches 100% but in the end it says it is impossible to complete the update and undoes the modifications. In windows update the error shown is 0x800f0922."

Things we share in common...
1) I also tried running the Media-Creation tool version of the 20H2 update.
2) I'm also on 1909
3) One other possible... thing that we share. He appears to be Italian. I am an American, however I do have Chinese keyboard installed. And I have a Chinese-Pinyin keyboard that installs itself using the japanese keyboard. I said this last one, because I've read some possible problems with the updates and language packs?!

It appears the Asian language packs might be the problem...
microsoft known issues

I figured out my problem...
I needed to solve my BCDEdit configuration. When I typed 'BCDEdit' it would say 'Device not found' and I would have to tell it where to find the store. Then when going into 'Advanced System Settings', the default-operating system was blank.
This also prevented Windows from updating. Fixed! I needed to rebuild my EFI partition... correctly.
I'm now on 20H2
