Cant deploy Windows 10 1703 on MDT 2013 with newer Windows 10 ADK

Question

Hello!

We have a issue at work with our MDT 2013 production server.

We were running a older version of Windows 10 ADK on our WDS server, were we could deploy etc. Windows 10 1703.

Then we made a new image with Windows 10 20H2, but we couldnt deploy it on the server, then we updated the Windows 10 ADK to the newest version and then the deployment of the new image was successfull, but now we cant deploy older versions like 1703 on the WDS server, how so?

We are running on older labtops like HP EliteBook 8460p, and when we deploy a new image on the laptop, we have to enable UEFI Boot in the BIOS, why?

because in a statement Microsoft wrote:

Will Windows 10 require UEFI and Secure Boot?

No, Windows 10 works just fine on legacy BIOS systems. New devices that that come preinstalled with Windows 10 later this summer must have UEFI by default and Secure Boot enabled at the factory.

Is there some kinda statement that after etc. Windows 10 20H1, windows cant boot unless UEFI is enabled in BIOS?

Hello @Steven Hansen

If the image was taken as UEFI boot, it will require UEFI in the destination hardware.
