Unattend file works with Windows 10 UEFI USB but not WDS

when use unattend file below on windows 10 uefi usb stick machine processes correctly creating disk partitions file , leaving me @ oobe.  this correct , expected.

when use same unattend file windows server 2012 r2 wds client unattend x64 (uefi) architecture , same machine still set use uefi following:

1.  client boots wds server
2.  i select language @ language selection
3.  enter login credentials
4.  select image install hit next
5.  next windows setup sits on "where want install windows?" screen instead of creating partitions unattend file can see @ following location x:\sources\wdsunattend\wdsunattend.xml

i can't seem wds process file though downloads wds.  any appreciated.

i've managed fix problem having.  hopefully find useful.

this works usb:

            <imageinstall>                 <osimage>                     <installto>                         <diskid>0</diskid>                         <partitionid>4</partitionid>                     </installto>                     <willshowui>onerror</willshowui>                 </osimage>             </imageinstall>

and works windows deployment services:

            <windowsdeploymentservices>                 <imageselection>                     <installto>                         <diskid>0</diskid>                         <partitionid>4</partitionid>                     </installto>                 </imageselection>             </windowsdeploymentservices>
