Windows 10: Windows 2004 update failed - Could not finish the installation

Windows 2004 update failed and now Windows will not start, only shows a message - Could not finish the installation.





My own translation:

"Could not finish the installation. If you want to install Windows on your computer, you can run the installer again."

I don't have an optical drive nor any bootable USB is there any way I can get around this?

The computer only has one drive with one volume (C but I have 2 VHDs that I can boot into (thanks @Kari) so it's no problem to access C: and make changes that way if needed.

I have tried several options on the "Recovery screen" but nothing has worked so far.

This Dell is 3 years and should be no problem, I thought. I have three much older PCs; 7-10 years old (Thinkpad, Asus & HP); and they all upgraded with no problem at all. (Amazingly that they still work with 2004 and with only 3-4 GB RAM.)

One difference that I believe should not make a difference is that this one has Dual boot (VHDs).

How do I go forward or revert to the old Windows version?

And Yes, all updates were offered by Windows Update.
And No, I don't have any backup...

Windows Updates failed to instal

I just did step one and they have just all installed.... thank you so much.... it was quite frustrating having that update window pop up every 5 minutes and failing to instal every time

Thanks mate

 

KB4025339 Fails Install 0x80070564

Thanks
I am trying Eagle 51's suggestions now. Windows Update troubleshooter found a bunch of errors and fixed all but one.The update is trying to download KB4025339 again. I'll see what happens. At step one troubleshooter finishes with one error unresolved "Potential Windows Update Database Error Detected-Not Fixed". Windows update stalled at 0%.

At step 2 same troubleshooter error. The KB finished a new download failed to install.
Did step 3 KB has downloaded but fails to install.

If Eagle's suggestion doesn't work I'll try EdTittel's suggestion

Tried bothe Eagle & Ed 's suggestions - do not work. Anyone else?

I have noticed that the latest update for my nvidia drivers has failed to update. Wondering about that!
