    Boot stops after cpu change, can't access GRUB

    Hello everyone, I installed proxmox on my intel system with an Nvidia gpu. I configured the system, so the gpu could be used by one of my VMs. It worked just fine but I decided to upgrade to an AMD ryzen 7 5700x cpu instead of the intel i5 11400. The mainboard used to be a Gigabyte B560M DS3H...
