Windows Update fails on one OS on my dual boot system.

Greetings from Australia!

On my dual boot system one OS updated fine to ‘Windows 10 Insider Preview 10.0.21390.1000 (co_release)’ ((I know…). But on the other older OS, ‘Build 21359.co_release.210409, which I had to reinstall from a few weeks old image (‘due to user error’) I keep repeatedly getting this message, “Error 0x80004005”.

I have both OSs on separate SSDs and have tried all the usual tricks on the net but no cigar.
I even disconnected all other drives but Windows won’t boot from the troublesome drive. I’ve changed the boot priority order in the BIOS but the machine will still not boot from this drive.
It seems the are certain necessary files on the other drive, meaning both drives have to be connected at the same time for the computer to boot.
The machine works fine except for the update issue on one drive.

Any suggestions would be much appreciated,

Mauri.

I have been trying to update my Windows 10 1909 to 20H2, with no success.  After 14 attempts to update, all 14 have failed.  I am getting the same error message you are getting, even though mine is a single-boot system.

I will check the actual error logs and get back to you.  Have you used Event Viewer?  If not, you can access it through the search window and get detailed information about the reason for the failures.

That happened to me when I installed 10 while other drives were in the system. I have no idea why.

Disconnect the other drives, repartition, reformat, and reinstall. Then reconnect the other drives.

Yeah, I had disconnect the other OS drive, delete and reformat the troublesome drive and reinstall. Hell of a job, it takes over two days to reinstall my workstation with it’s huge amount of audio software… and the darn authorisations…

I think the problem, particularly with dual boot systems is that Windows ‘shares’ files with other drives in the system. With my setup, even when everything works fine I can only boot up from one of the drives via Windows boot manager which obviously shows the two OSs as options. Which means only one of the OS drives has the necessary file(s) to boot the system.

Thanks for your interest, guys,

Mauri.
