[SOLVED] Windows 10 20h2 no longer upates (missing partition?)
Hi,
I've recently noticed that my Windows Home v20H2 19.042 repeatedly cycles in trying to install the 2021-05 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5003173) but after what seems to be two attempts to apply the update separated by restarts, it undoes any change and reverts to the previous situation. The Settings panel mentions the update error code 0x800f0922. Then tries again the day after (download/install/wait to restart).
Aside from this, once reverted, the PC runs fine. I have no errors with the "sfc /scannow" check.
For a bit of context that would likely be at the root of the situation, I did one month ago, with the helpful assistance of this forum, completely got rid of and free-up a HDD where the OS was initially installed on, after having moved the OS and EFI partitions to the SSD. I wonder if some required partition isn't missing (Recovery ? other system reserved ?) which was on the HDD formerly but got wiped.
As complementary information:
- The msconfig application shows nothing in the list of OS's under the boot tab
- Running bcdedit /enum command returns following error message:
The boot configuration data store could not be opened.The requested system device cannot be found.- When forcing the computer to enter the advanced startup mode, the displayed menu only shows "Power Off", and not the "usual" made of these "System Restore", "Startup Repair", "Command Prompt", "System Image Recovery", "Choose Another Operating System", etc...
- Visual BCD editor won't even start (claiming to require admin credentials, while they are provided)
Am I right assuming a required partition is missing or do I not need it and would a configuration change suffice ?
Thanks for your precious advice !
This is what the Windows disk partition tool looks like now:
And this is what MiniTool Partition Wizard shwos at start-up:
Additionally, these are the info collected by DiskParInfo.bat : (don't know why it all appears on a single line despite the CR/LF characters are there !?)
