[SOLVED] Windows 10 x64 KB4462919 failing with error 0x800f0922

[afung]

So my Windows 10 recently started trying to install KB4462919.
It will try to install, reboot, will fail at 34%, reboot again and roll back.

It will retry the next day automatically and fail the same way. And now it has failed 7 times as indicated in the Windows Update settings page.
I also tried download KB4462919 and install it manually. It failed the same way.

I followed the steps in the posting instructions.
Here are the results:

Step 2: No Error
Step 3: No Error
Step 4:

Hello and welcome! Is there free space on your system reserved partition?

System reserved partition is the FAT32 partition containing EFI boot files right?
That partition has 71MB of 96MB free.
Recently I cloned the system disk from another SSD. Would that be related?

Thanks.

Correction: I found that my pc did NOT have a Microsoft reserved partition.
I cloned the system without the msr.
What I did:
used diskpart to clean the new SSD, convert gpt, created a 100MB FAT32 partition, then clone the NTFS windows partition from the old SSD to the remaining space of the new SSD.
used bcdboot to create boot files on the FAT32 parition, removed the old SSD.
PC booted successfully using new SSD after that. I thought all is good.

Is there a way to recreate a usable msr? (old SSD already formatted, can't clone/restore)
I tried one thing:
- shrink the windows partition
- diskpart => create partition msr
- now my disk has 4 partitions - reserved 15MB, FAT32 primary 100MB, windows partition 931GB, reserved 100MB
- retry the windows update again but still failing
I guess windows does not recognize the reserved partition(s) because they are probably empty and it needs the old files?

Thanks.

Update: found a solution myself
- Booted to a windows installation USB
- Used Diskpart
- deleted the original FAT32 partition
- ran "create part efi size=75" size is smaller than the original FAT32 partition
- format fs=fat32 quick
- ran "create part msr" to fill up the remaining 25MB space
- ran bcdboot to create boot files to the EFI partition
- re-ran the windows update

Read somewhere that the reserved partition must be right after the EFI partition...

Yes, I suspected that myself! Excellent work!
