I have two lenovo models the X1 Yoga and the T470 that I am PXE booting and deploying windows 10. The Drive does get successfully partitioned and the OS does apply. The problem I am encountering is when the ADMIN account does it's first logon and the MDT bundles continues with it steps - on the T470 only it will fail because it's trying to use the D drive which Windows is hijacking and saying is being used by removable media... except that it's not. There is no other media in the computer. I do not have this problem on the X1 Yoga with the same deployment.
The D drive seems to be randomly picked by the MDT bundle as I am not assigning it and then Windows Hijacks it for this mysterious drive.
