Windows 10 Updates Always fail with message "Could not complete updates, reverting changes"

My PC has been doing this for probably a month or more. It gets an update notification every day. When I install the update, it proceeds normally, but fails right at the end and says "reverting changes, do not turn off your PC". The update notification then disappears until the next day, presumably while it downloads the update again.

I have tried several fixes posted online such as deleting the update cache and restarting the update service, but they haven't helped. What I would like to do is look at some sort of log file and figure out exactly why it's failing. My PC has a pretty complicated configuration, so it could be anything.

I'm dual booting, with 2 versions of windows 10, 1 is enterprise, and the other is pro. They are on different physical drives. The PRO version is never updated or connected to the internet. The enterprise version is what I use most of the time, and it's what I want to update.

During the update the machine has to restart. This brings it to the windows OS selection screen; which I thought might cause problems, but when I select the enterprise edition OS, the update continues as you'd expect, up until the point where it fails.

I also must admit that I have a habit of disabling windows services that look unnecessary (for example windows store or xbox related stuff). That does sometimes cause issues when I kill something that I shouldn't have so just throwing it out there.

I tried using the Get-WindowsUpdateLog command in powershell to generate a log file, but it's extremely long and I don't know exactly what to look for in it. I see some failures but those might just be temporary network issues or whatever.

Edit: Here are the most recent entries from Get-WindowsUpdateLog after a failed reboot. I can post more if needed.

Edit2: When I got back to the update settings screen after a failed update, it shows the error code (0x800f0922).

Edit3: Here's my partition table: I'm fairly sure MAIN_OS (the OS I'm trying to update) is the primary.

If you need update your windows 10 enterprise device update to the latest version, I would suggest you download Windows Update Assistant from the following link and have a try. The Update Assistant can help you update to the latest version of Windows 10.
