I have a dual boot laptop with Windows 10 and Ubuntu 16.04 - with the following partitions : 

Disk 1 - 128GB SSD : 
        160Mb EFI System boot partition
        128Mb - msftres (no idea)
        60GB - Windows 10 (C:\ - 23GB free)
        1 MB - unused
        1.5GB - ext3 - /boot
        20GB - ext3 - /
        20GB - linux-swap
        18GB - ntfs - shared game assets
        500Mb - ntfs - windows recovery - 200Mb free

Disk 2 - 2 TB
     128Mb - msftres
     1TB - ntfs - (D:\)
     900Mb - ext3 - (/home)

I have grub installed which allows me to boot whichever I wish.

From the Middle of March I have been prompted on windows to install a new version (Windows 10 is version 1607 currently).

Update attempt 1 to n: Using Windows Update Assistance

I tried downloading as prompted, which downloaded ok, the machine restarted - I chose Windows from the grub menu; it started installing - reached 25% and restarted again. Chose windows again from grub menu - windows restored previous version - no update.

I tried the Windows update troubleshooter - it found and 'fixed issues'; tried the update assistance again - same result. Ran the trouble shoot again, same issues found and fixed; tried again as above - same result - rinse and repeat every few days.

Update attempt 2: Using Windows Media Creation Tool

Using the tool, I burnt and verified a DVD - and booted my machine from that DVD; the DVD software could not even detect Windows on my machine despite it being fully authorized and licensed.

After this failed attempt - booting into windows gives this error :

Windows Error - post DVD update attempt

Needless to say this error code don't seem to exist on Microsoft's web sites. - it is odd that this error is generated when the DVD claimed it couldn't even find a Windows version - but clearly it found something in order to trigger this error.

Running the Update Trouble shooter - again it claims to finds the same set of errors as it did previously - suggesting that the Trouble shooter is mostly pointless.

Where Next ?

So the big Question - How on Earth do i get windows to install this windows update ? [previously windows updates have always worked (even when they required a reboot), but this one just fails].

Additional Info

  • looking at the Windows Event Log - there is no log message of any of the attempted upgrades, or any error message from any of the failures and windows re-versions.
  • The machine uses UEFI - if that matters
  • Laptop has 32GB RAM

  • For Windows updates from ISO, I've had better results with a USB device made with Media Creation tool than with a DVD, since DVD drivers were not available from UEFI... though if you could start booting from DVD, that is not likely the issue. – DrMoishe Pippik Apr 27 '18 at 16:15
  • @DrMoishePippik *not likely the issue*... It depends. If the UEFI settings allow for Legacy/CSM (typically UEFI+Legacy instead of UEFI Only) then all bets are off, either a DVD or a USB can end up being booted in Legacy mode in which case it won't detect the installed OS. –  Apr 27 '18 at 16:31
  • I should have said - my laptop is fully capable of booting from the DVD. – Tony Suffolk 66 Apr 27 '18 at 19:05
  • remove GRUB, update Windows 10, reinstall GRUB. Windows doesn't like other bootloaders. – magicandre1981 May 02 '18 at 15:35
  • @magicandre1981that is despite the promise by Microsoft that they were going to play nice with other boot loaders ? Given that the Troubleshooter app comes up with the same issues over and over again - I am not sure that it is the boot loader that is the problem .. – Tony Suffolk 66 May 02 '18 at 16:28
  • Microsoft never promised this. I also had to delete the android x86 boot entry to update to 1709. I reported it to Microsoft, so try the [1803 upgrade](https://blogs.windows.com/windowsexperience/2018/04/30/how-to-get-the-windows-10-april-2018-update/) maybe they fixed it here. – magicandre1981 May 03 '18 at 15:06
  • I have no way of selecting which upgrade I get - in fact I don't even know which one is failing - failed upgrades aren't reported or logged in anyway - yet another microsft commitment to qualifty .... :-( – Tony Suffolk 66 May 04 '18 at 11:46
  • you get the forced 1709 upgrade. Delete the hidden **$WINDOWS.~BT** from C:\, [get the 1803 ISO](https://superuser.com/a/1108086/174557), mount the ISO and run setup.exe, select upgrade/keep everything – magicandre1981 May 04 '18 at 14:32
  • have you tried the 1803 update? does it also fail? if yes, use [SetupDiag](https://docs.microsoft.com/en-us/windows/deployment/upgrade/setupdiag) to analyze the logs of the failed update. – magicandre1981 May 06 '18 at 19:26
  • @magicandre1981 - i haven't had a chance to try it - holiday weekend spent with the family :-) - will try it this week i hope. – Tony Suffolk 66 May 08 '18 at 14:15

Microsoft never tests Windows Upgrade (the Feature Updates of Windows 10 are new Windows version, so the update is doing an upgrade like Vista to 7 or 7 to 8) when a different boot loader is used.

When I did the upgrade from 1607 to 1709 on my 8" Toshiba Encore Tablet, I also needed to disable the Android x86 boot entry otherwise the setup also failed. I submitted it to Microsoft so try the 1803 ISO/Installer if they improved it now.

If this also fails and running SetupDiag to analyze the log files uninstall GRUB, update to 1803 and reinstall GRUB boot loader.
