Hi, Given the changes that proxmox makes to grub running does anyone know the process to add more entries to the grub menu please ? I tried grml-rescue to no avail. Your help would be appreciated.

I need to launch Memtest86+ at startup of my Proxmox machine. I manage to add it to Grub, but then I don't know how to add it to systemd-boot. I do "proxmox-boot-tool refresh" and only available kernels are added, not Memtest86+. Any ideas?
