sanboot makes the ISO visible to UEFI but invisible to the Linux kernel after ExitBootServices(). Switch to direct kernel/initrd boot with a small CPIO overlay containing /pxe-init — a shell script that loads NIC drivers, configures DHCP, downloads the ISO via wget, and creates a loop device before handing off to the Proxmox installer init.
