Scripting

My K2000 has been doing scripted installs to late model Optiplex's and Lattitude E7440 and E7450 systems.  This afternoon I got a new Dell Precision T3420. Of course it won't boot in my current KBE environment so I called KACE support and the tech recommended creating a WinPE10 based env.  Copied up the files, recached and created the environment.  System won't boot.  Bombs on iastor.  With the help of some other posts here in this form I created another environment using the Driver packs 4 and 5.  So now I have a working KBE boot environment that boots the T3420.  BUT...... I select my standard image of Win7_64 and the process immediately bombs on creating the 1st 2 partitions (C: and D:).  No problem, I'll just temporarily create them myself and move on.  Finally got that fixed the image is deployed and finishes.  When I login to the system afterward, the image is correct with all the application installed but their are no drivers installed.  Device Manager shows exclamations for all the drivers not installed.
