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.

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.
