UEFI Interactive Shell appers

Maybe someone able to help me.

After I had to move my HA VM (Oracle VM VirtualBox) from one drive to another drive I getting on starting the HA VM the “UEFI Interactive Shell” window.

I am able to start HA going into ‘Boot Maintenance Manager’ and selection in ‘Boot from File’ file bootx64.efi

But what I have to change that HA is starting automatically after a VM restart as before?
