At first my Specs:
Msi Meg Unify x570
Palit Gtx1080ti Gamerock Premium
HyperX Fury 16GB 3200mhz cl16
NZXT E850 Power Supply
970 Evo 512GB
WDC Blue 512GB
Sandisk 1TB Sata SSD
What´s the Problem:
I can´t get my System to Boot into Windows if a Bios version with Agesa above 220.127.116.11 ABBA is installed.
At first i thought the Problem is Asrock´s messy Bios (swapped the X570 Steel Legend for the MSI Unify after that).
Yesterday, after installing the Meg Unify i imediatly updated the Bios to the Latest Version (A42(Agesa 18.104.22.168)) and did a system wipe with a fresh Windows Install.
Everything Works fine until a Displaydriver is installed. The system then crashes as soon as the DD is installed, and will bootloop into Windows Repair.
Safe-Mode will boot up normaly.
If i uninstall the DD via DisplayDriverUninstaller i can Boot into Windows as usual (until a DD is installed again).
So then i tried the fix that worked for my Steel Legend Motherboard. I flashed the A00 Bios (Think it´s kinda Agesa 22.214.171.124 or so).
Windows will boot as usual even if Displaydrivers are installed.
So everything in Short:
Bios with Agesa above 126.96.36.199 Abba + Displaydriver = Bootloop
Bios with Agesa above 188.8.131.52 Abba - Displaydriver = Boot success
Bios with Agesa 184.108.40.206 Abba or below + Displaydriver = Boot success
