Win7 Install USB freezes at Starting Windows

what do I need to do? Ive used the AMD_AM4_X399_TRX40_Drivers_B12_Win7_8.1 driver package with ntlite, but yeah it freezes.

EDIT1: ive created the windows usb stick with rufus btw, gpt and ntfs
EDIT2: but when enabling csm mode in bios i get new error, the same freeze but after that i goes to a bsod and says, bios is not fully acpi something
EDIT3: im using a RX 570, igpu is disabled

You are not the first Forum member, who tries to get Win7 installed onto a PC with modern hardware, which natively may not be Win7 compatible.
Good luck!
