<< Solved >> Catalina 10.15.2 installation woes

[esafeddie]

Hey, thanks for you answer, this is my new setup:

Mobo: Gigabyte Z390 Aorus ULTRA
CPU: Intel Core i7 9700F
RAM: Crucial Ballistic 2x16GB DDr43200 MHZ
SSD: 1TB Intel SSD 6 M.2 NMVe
GPU: Asus Strog Rix AMD RADEON RX 5700 XT 8GB DDR6.
PSU: EVGA 700W Bronze 80plus

Just tried many Bios setups and many Bios Version. I'm already installed the NVMe in my old setup, then the installation went smooth... Now everything works fine in the new setup. I cannot not figure it out!
All ideas are welcome, I'm still testing!
Thanks mate

That is indeed very strange, why it works in one and not the other, I still think it points to either incomplete BIOS settings or hardware failure/incompatibility. Is there a way for you to test using Clover boot loader instead of Opencore, possibly using a SSD drive instead of a NMVe drive?

Hi Mate! I found it out! The problem is the GPU (MSI AMD RADEON 5700 XT 8GB OC). I'm using boot arguments agdpmod=pikera, anyways there's something to patch in there...
Today I got a RX 580 for my old build, and the installations problems are gone with this GPU! I found this while I attempted to install the 10.14.6 public beta update in the new build!
Thanks for your help!
