Blackscreen while installation "Windows loading files"

Hello,

I am trying to boot Windows 10 from a DVD, but after the loading bar "Windows is loading files" is finished, the screen remains black. (I mean first Windows DVD boot screen, not the standart Windows booting screen!)

The problem seems to occur more often, but so far I have not found a solution.

Has anyone already solved this problem?

My Mac is officially no longer supported, but the DVD boot method usually works fine with Windows 10 on the Mac Pro 3.1!

Here are my specs:

Mac Pro 3.1

2x3,2Ghz Quadcore Xeon

32GB Ram

Nvidia GTX 770 4GB

Original Superdrive (Internal)

I use the latest Windows 10 (64-bit) ISO from Microsoft.

How I proceeded:

-Bootcamp -> USB 2.0 stick (FAT32 master boot) with Appel driver.

-Harddrive for Windows FAT32 formatted

-Windows 10 DVD to the SuperDrive drive

-Restart with ALT

-Picking Windows DVD image

-Windows is loading files

-blackscreen

The USB 2.0 Stick plugs into the standard Mac port.

The HDDs are set in the standart Slots (No SSD PCI Slot).
