installing windows on mac locks when loading files

Booting this USB Windows installer (in EFI mode) in my Mid 2013 MacBook Air 6,2 works just fine, and launches the Windows installer, so I know the USB stick is working just fine.I removed the 'bootmgr' and 'bootmgr.efi' files from the USB stick to avoid BIOS/CMI boot and force EFI boot.

USB stick made bootable using the method described in link above, and then copied all the files from the ISO.

Downloaded the Windows 10 圆4 ISO directly from my Microsoft business account.

The remaining disk was GPT formatted (no MBR present).I removed all disks from my MacPro, except for one fI wanted to install Windows 10 on.My MacPro is a native 2010 MacPro5,1 Model, not some hacked 2009 4,1 firmware upgraded to 5,1.Yet I read the article HERE where a user named '2000one' posts a detailed description half way down of how he got it to work on a 2009 model MacPro4,1 upgraded to 5,1. I am trying to install Windows 10 圆4 in native EFI mode (not BootCamp) on my MacPro5,1 from 2010 with no luck. I am hoping someone can solve this once and for all, because I have been going crazy with the conflicting information I keep reading on-line.
