Cannot import Win10PE boot image into SCCM

HI I'm running SCCM 1511 console, with DCIS 4.2 installed.  Also have Windows ADK 1511 installed.  All on Windows 7 x64 machine.

2 questions:

1) When going thru import wizard, it asks for a boot image to modify.  Is that right?  Seems odd that it wouldn't create it's own like a driver package does

2) I get the error "The selected boot image is not compatible with the installed Windows ADK"

Also tried the 1607 ADK, get same results.

Anyone have this issue?

Tony
