Windows 7 Downgrade Help

I have a Windows 8 Zoostorm Machine (and I am trying to downgrade to Windows 7) with the following spec

Intel Core i3-4130 Dual Core CPU - 2 x 3.40 GHz

Nvidia GeForce GTX 760

8GB DDR3 1600MHz
Windows 8.1

It has Gigabyte DualBios UEFI

I have purchased a Windows 7 Licence and CD,
Note - it is not SP1 Install CD.

I disabled Secure Boot and disabled Intel Virtualization

But then when I enable CMS the BIOS boots as a blank screen (connected monitor is via VGA) so I am unable to proceed through the options on Windows 7 setup because it's a blank screen

I'm then forced remove to
small battery in the PC to reset the BIOS back to default

What do I need to do to install Windows 7

Please can someone help
