After Windows 10 WIM deploy, system fails to boot

I have some brand new notebooks (they are HP Z Book G4 Studios). From the state I received the units, I wanted to deploy the company image, instead of using what came loaded by the factory.

Before posting, I did search this site and I did look at: https://social.technet.microsoft.com/Forums/en-US/a93391aa-de01-4548-8568-f9cfd39cf641/applied-wim-file-does-not-correctly-boot?forum=winservergen

No help.

Deploying the WIM failed. It's a Windows 10 WIM. The WIM had the HP drivers added to it... if there was a problem with the drivers, I would expect a BSOD. But that is NOT the problem as no BSOD is received.

Here are the steps I took:

1. Press F9 to access boot menu
2. Connect USB DVD drive with WinPE disc inserted
3. Boot to WinPE (created with the latest version of the AIK/ADK or whatever MS is calling it these days).
4. Run the following diskpart commands: select disk 0, clean, create partition primary, format fs=ntfs quick, assign letter=c:, and active
5. Run dism /apply-image /imagefile:e:\myWIM.wim /index:1 /applydir:c:\
6. Run bcdboot c:\windows /s c:
7. Exit WinPE and reboot.

After exiting and the subsequent reboot, I get an OS not found error right after POST.

I booted into the installation media, rescue mode, and ran:

bootrec.exe /fixmbrbootrec.exe /fixbootbootrec.exe /rebuildbcd

The bootrec.exe command returns:

Successfully scanned Windows InstallationsTotal identified Windows Installations: 1Add installation to boot list? Yes/No/All:

So I enter Y

...and it fails!!!

I can go to c:\ and do a dir and see the file system as expected (so again, assuming so WIM integrity problems).

1. Is there anything special about doing this on Win 10 that is different (Win 10 does put a 100 MB and 450MB partition on the drive when it does a clean install right? Recovery areas and such?

2. When I do the diskpart clean, that wipes those two partitions out. How critical are they to run?

3. I've used the same process which worked on Windows 7 -- are there BIOS settings, partitioning, etc., which is preventing this from booting for me? I haven't had such problems before; just with Win 10.

The drive from the factory was gpt. I did run diskpart convert mbr. The whole process failed in the same way

Suggestions are greatly appreciated!

Thanks!!!
