Cannot update to Windows 10 Anniversary

Hello,

I am trying to update the Boot Camp partition on my late 2014 Mac mini. I am using the Windows 10 Upgrade Advisor. Everything seems to be working ok but when the update is done and I boot back into Win 10 I am back to the previous version, 10240. I suspect this has to do with the Intel Iris 5100 graphics driver. I ran into this problem with a previous update and was able to get through it by deleting the Iris 5100 graphics driver. This does not seem to be solving the problem this time around.

Anyone got any ideas?

Mac mini, OS X El Capitan (10.11.1)

Is this from the 1607 ISO available from Microsoft? If not, can you post the name of the file your are using?

I am not trying to install from an ISO. I am trying to upgrade an existing Win 10 install using the Windows 10 Upgrade Assistant.

The latest build from Microsoft breaks a few drivers. For example http://news.softpedia.com/news/windows-10-anniversary-update-might-hide-partitio ns-after-install-507247.shtml . The Intel GPU driver may still be in your driver store. Can you uninstall the driver, remove the GPU, use pnputil to remove the driver and fall back to the Generic Display driver and then re-try the upgrade?

Thanks Loner T. I think that's pretty much what I did. I'm not familiar with how to remove the GPU or use pnputil, but I deleted the driver in Device Manager, and then without rebooting tried to get the upgrade. This worked for me previously when I got hung up on a Win 10 update.

Are there additional steps I should be taking here to avoid the graphics driver hang up?

After you uninstall the driver, in Device Manager, right click on the GPU under Display adapter and remove (without reboot) and then try your upgrade.

When I uninstall and delete the driver the Display Adapter is no longer shown in Device Manager. Windows Upgrade Assistant proceeds through the upgrade but when it reboots I very briefly see a screen where Win 10 seems to be configuring, then it reboots abruptly and I'm back to square one.
