Unable to install Proxmox: Garbled text after Starting Proxmox installation

[FortuneCookie101]

I'm trying to install Proxmox on a new build PC via bootable USB and as soon as it hits "Starting Proxmox installation" the text garbles and becomes unreadable.

Things I've tried so far:

• Ctrl + Alt + F(N) to switch to a different X window, all the same garbled mess.
• Booting with debug options noacpi, noapic, vga=normal etc.
• Checking the ISO and re-imaging the usb.

I'm assuming it's a driver issue as I'm able to get a console just fine in debug mode.

Update: I noticed the log stating "nvidiafb cannot request pci regions" before switching to the screen in the screenshot. Starting it with boot option "module blacklist=nouveau" stops the garbled text appearing but it seems the graphical installer doesn't start.

So whats the available graphic cards in this PC? Only NVIDIA ones?

Only the RTX 2060 unfortunately.

Solved by installing Debian first and then installing Proxmox. I had to add module_blacklist=nouveau to grub default otherwise the same garbled display will show.
