Okay, your tutorial is great and I understand the issue with most people is when they try to install Windows 7, their keyboard and mouse is either frozen or the hard drive is not visible and that's because drivers need to be injected.
My issue is at the initial boot phase. Because I have done everything that you have nicely laid out in that tutorial but I cannot boot from flash drive.
The error that I get is \EFI\Micosoft\Boot\BCD 0xc000000d.
Osprey brought up an interesting point where he mentioned that Windows required INT10 and if the motherboard doesn't have that, it's not going to work.
But the question now is, why does it work from a DVD but not Flash Drive? On a motherboard where INT10 is not present.
By the way, using diskpart to prepare a flash drive did not help so rufus may not be the issue.
Since the original Microsoft disc works, now i'm preparing my 8GB iso for a dual layer dvd. We'll see if it works.

Unbelievable! It works from a DVD.
I'm gonna dig a little further to understand WHY and if a USB install is even possible.
The first guess that comes to mind here is that the Windows 7 UEFI installation files (USB only) do not have the mechanism to handle motherboards where INT10 is not present.
So the next test is going to be : USE Windows 8.1 setup files with a Windows 7 wim and see IF that works from a Flash Drive.
Doesn't look like it's doable and it all goes back to the INT10 and VGA.sys.
I'm poking around into loading HIVES from the WIM files and delete VGA.sys services which don't work on UEFI motherboards.
I think it's pretty clear to me at this point that we have to say Goodbye to Windows 7 on new UEFI hardware with no BIOS emulation since Windows 7 is not fully UEFI compliant.
