how to fix windows 10 x64 post sysprep error 0xc0000001 inaccessible boot device

I have successfully sysprep'ed hundred of times in the past with previous versions of windows.

I have many HP Z400 with 8gb of RAM, and they are all identical. The only difference is the source system has 1 hard drive and destination has 2.

I made the image, backed it up, and used sysprep. Captured and deployed the image.

Issue 1. All 25 computers get 0xc0000001 inaccessible boot device. I checked the boot order although that was never changed, it was correct. I disconnected the 2nd hard drive and they get past that error. The 2nd hard drive is a non bootable GPT 3tb hard drive just for storage. The hardware does not support bootable GPT or UEFI.

2. After unplugged 2nd, it gets to sysprep, and after running a while and completing the device stage it says Windows can not be installed on this hardware......

   What?? The same computer just had windows 10 on it and it was just fine, 10 minutes ago. I know windows 10 want UEFI and GPT, but the Z400 doesn't support it. The same exact hardware had windows 10 running just fine before sysprep.

   I can get the Advanced recovery options, but the approx 7 options there including safe mode do nothing. Start up recovery says it can't do anything about it. I check the logs and all the hard drives are ok. The log file claimed my Start up repair was the wrong version.

   How can that be?

   Booted off the install DVD and did Start up recovery to no avail.

   Deployed my back up of the pre sysprep, and it also fails to boot with 0xc0000001 with the 2nd hard drive plugged in. Unplug the 2nd hard drive and it boots just fine. Connect the 2nd hard drive post boot, and the system seizes up, and fails to respond.

Suggestions?
