[SOLVED] Rebooting at Loading initial ramdisk if no external GPU is installed

Hello, new user here trying to migrate from Esxi!

I have a strange issue when installing or running Proxmox.
I use an Intel(R) Core(TM) i7-8700K CPU with a Z370 AORUS K3 motherboard.

The issue is that I can't install or run Proxmox without installing a dedicated GPU.
I'm using the internal graphics to my monitor so the GPU is not being used.
Tried upgrading bios, a bunch of settings but it always reboots when Loading initial ramdisk if I remove the GPU.

Does anyone have any ideas on what the issue could be or how to troubleshoot?
I can't see any logs since it reboots.
