My Server is down with error: file '/boot/grub/i386-pc/normal.mod'

When I try to launch the console from panel I get this error: file ‘boot/grub/i386-pc/normal.mod’ not found. And prompt of “grub rescue” comes. I have no idea how to resolve this issue. Here is what I have tried so far: 1. I tried this option https://unix.stackexchange.com/questions/70538/grub-error-file-grub-i386-pc-normal-mod-not-found https://askubuntu.com/questions/266429/error-file-grub-i386-pc-normal-mod-not-found 2. The above links suggested to change the prefix I tried, but it didn’t worked, here is the output of ls. grub rescue> ls (hd0,gpt1)/boot ./ …/ efi/ grub rescue> ls (hd0,gpt1)/boot/efi ./ …/  NO FILES/FOLDER inside efi folder and there no grub folder as well. So I think grub is removed. And I have no idea why/how.
