drivers cannot be found at installation of Windows 10

[ebc-marburg]

Hello folks,

in order to install Windows 10 from a network share I made the entries in boot.ipxe as given in http://ipxe.org/howto/winpe to load WinPe environment via tftp.
It boots as it should but there is a problem in the installation process namely that drivers cannot be located.
From earlier configurations by someone else there is also a Windows 7 subfolder which directory tree looks similiar to the result given by https://technet.microsoft.com/de-de/itpr...windows-pe (sorry, i cannot find the english article now).
Nonetheless I am not able to work out a solution not to mention to get a hint why drivers are missing or what i should do in order to progress further.

I thank you in advance for any hints or links.
