Install Windows 7 Pro on 750 400GB NVMe

I'm been trying to install Windows 7 Pro onto this system:

ASUS Maximus VIII Z170 Chipset Mainboard

Intel 750 MVMe PCIe SSD

I've updated all the drivers, firmware but when I boot from a Windows 7 DVD, I ask it to load the Intel Drivers, it scans for drives and then tells me that there are not acceptable drives to install on.  The WIN7 DVD is in a DVD-RW connected to an internal SATA port and the driver on a USB stick. 

I've followed the instructions from the SSD support page for the drive:

http://www.intel.com/content/dam/support/us/en/documents/ssdc/hpssd/sb/nvme_boot_guide_332098001us.pdf

As a test was able to load Win7 onto a SATA SSD and then load the NVMe driver.  Worked fine and I was able to partition and access the NVMe 750 drive.

any help would be appreciated .  Windows 8 or Win 10 are not an option as the main use software requires windows 7 pro.

THanks.
