Windows 7 on Helix2 (20CH)

By any chance, has anyone managed to install Windows 7 on a Helix2 (20CH)?  Currently have a loan model to try out and for business reasons need to install Win7.  - If at all possible.


As the BIOS is UEFI only.  I am having issues getting the OS to install by either modifying the Win7 ISO as per this tutorial:


...or by using MDT 2013.


I keep getting the following error:


Windows Boot Manager


File: \EFI\Microsoft\Boot\BCD

Status: 0xc000000d

Info: An error has occured while attempting to read the boot configuration data.


Any suggestions greatly appreciated!?

Helix 2nd-gen does not support Win7.  Even in UEFI mode, Win7 requires a Compatibility Support Module (CSM) which Helix 2nd-gen does not have.
