After I upgraded to PVE 7.3-4 from 7.2-4 and rebooted my system now shows this error and doesn't boot.

The boot partition only has a EFI folder and seems to miss a lot of things.

Is there a way to recover this node? Like booting from a Proxmox ISO and doing any recovery/boot fix?
Does anyone knows a way of creating a fresh new boot partition with grub?

I've tried with the procedure published here: https://pve.proxmox.com/wiki/Recover_From_Grub_Failure and also a proxmox-boot-tool init procedure, but commands always fail complaining about missing files, folders, etc.

Please help, it's my main NAS.

I'm still stuck with this problem...
Cloned sda1 & 2 from other working proxmox install, and logically now it complains that it can't find the os partition and goes into grub rescue.
I don't know what else to do.

Booting from install in debug:

efiboot-tool fails:
