System can't boot after the latest update

[Johnp34]

After the latest update my server don't boot and i get the message "Reboot and select proper boot device or insert boot media in selected boot device and press a key". The booting disk shows up in bios but i can't boot the system. Is there any solution besides reinstalling proxmox. Thanks in advance

• What's your version of PVE? (pveversion -v)
• Which kernel does it try to boot?
• Does the system boot with an older kernel?

I don't remember but i suppose that is the latest.

I don't have access to the system

Do you mean "right now" or "at all"?

• Can you try to boot with an older kernel?
• Do you boot using grub oder systemd-boot?

I can't boot at all. I get the error "Reboot and select proper boot device or insert boot media in selected boot device and press a key".
I booting with grub
