The issue is Upgrading Windows to the newest build version via Windows 10's Windows Update. I can dual boot Windows 10 and Arch Linux perfectly fine. It is just that I cannot upgrade Windows 10 using Windows Update through normal means.

Normally what should happen is that I go to Windows Update and there is a new Insider Build to download and install. I would let it download and press "Install." After it does it configuration, I would press "Restart" and Windows would do its upgrade. However, after I press "Restart" it never upgrade and I do not know why.

Is there a Upgrade Log file that I can read so that I can at least know what is going on? I think this is more of a Windows problem rather than Linux as the upgrade process, which should have ran after I boot to Windows, did not run correctly or there was an issue somewhere. 

EDIT:

Also note that if I am on Windows Bootloader, the upgrade process works perfectly fine so maybe GRUB is not running the installer or points to Windows OS rather than the installer? 

I do not use Achi Linux to be able to test it but you might like to try this if you do not find any other suggestion.

When you update to a new version of windows, press shutdown rather than restart or shutdown & update.

Then boot into Arch Linux and fix grub to be able to chainload the windows boot loader.

Then reboot in Windows and this time go back to windows update and restart & update.

https://wiki.archlinux.org/index.php/GRUB

Chainloading Windows/Linux installed in UEFI mode

insmod ntfs
set root=(hd0,gpt4)
chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi
boot

insmod ntfs used for loading the ntfs file system module for loading Windows. (hd0,gpt4) or /dev/sda4 is my EFI System Partition (ESP). The entry in the chainloader line specifies the path of the .efi file to be chain-loaded.

Hmm... just checked my GRUB configuration for Windows. My Windows is a Legacy so the UEFI does not work, I have to use something like

set root=hdX        # where "X" is the hd number for Windows

chainloader +1

boot

Note for those who wants to try this. To access this ability to chainload, you must enter GRUB's command line via GRUB's boot menu (normally by pressing "c" on the menu). Although I think GRUB sets this automatically.

It appears that my GRUB configuration was already like that too. So I do not think that this will help too much... but

Unfortunately, I ran into another mini problem with Windows Update: Error 0X80240031. It must be because I was deleting the installation files so that I can force Windows Update to do a fresh download. This sucks because I really want to find a permanent solution to this problem.

Right now I am just going to download the ISO file for the build 14295 and install via USB. Though if I remember correctly (I did this for a previous build before), I will probably run into the same error... will keep up to date as I progress.

Though I do have a notion of a fix. Let see if this works...
