Windows Server 2016 core error

Wilco

Hello,

When installing Windows Server 2016 Core on an Up Board Windows gives a error on the first time booting up.
It give the error INACCESSIBLE_BOOT_DEVICE.
It shutdown and keeps trying to boot up.

The Windows Server 2016 GUI installation has no problems and works fine on a Up Board.

We think it's a driver or UEFI problem.

Does any one have a idea to solve this problem?

We found the solution.
Windows Server Core 2016 is missing drivers for the MMC card.
It are the drivers sdbus.inf en sdstor.inf.
Adding them to the Windows ISO and installing Windows works.

To add the drivers we extract the inf and sys files from the GUI version and them to the Core version.
In total 5 files

Windows\INF\sdbus.inf
Windows\INF\sdstor.inf
Windows\System32\drivers\dumpsd.sys
Windows\System32\drivers\sdbus.sys
Windows\System32\drivers\sdstor.sys

To extract en add them we used this guide as reference

Thanks for the hint that this driver is just missing. With a lot of help in this gist https://gist.github.com/PatrickLang/820aa9e8c60654da051c139fb245fae8 (thanks Patrick!) I wrote down all steps that worked for me to create a bootable USB stick to install Windows Server 2016 core on an UP board.

My pleasure. The steps are all most the same steps that I used.
Personally I used Rufus https://rufus.akeo.ie/ to make USB stick and edit the WIM file directly on USB stick.
But your method works just as good.

Hi,
It does work with Windows Server 2016 Core, but does not with Hyper-V Server 2016. I guess it misses some other driver. Can you tell me what else is needed?

Wilco

I don't know which drivers are needed for Hyper-V Server. But what you can try is to copy all the drivers that are missing from Windows Server Standaard 2016 to Hyper-V Server 2016. Just copy all the drivers to a folder and at them using dism.exe. If you want too know which driver it is exactly you select a
couple of drivers until it works a again. Keep doing this until you find the missing driver.
