Same issue here. It stops and then makes all the text pixelated and shows "support.apple.com/mac/startup". With a cross/not allowed sign.
Specs:
- CPU: Intel Core i9 11900K / Codename "Rocket Lake"
- GPU: NVIDIA GeGorce RTX 3090
- Mainboard: NZXT N7 Z590 / Chipset "Rocket Lake"
I replaced the EFI with the Desktop Rocket Lake EFI. Cleared VRAM. Disabled TPM and Secureboot. And SATA is set to AHCI.
