I have a remote server, which I have no physical access to. I rebooted the machine over the weekend and it's now refusing to boot, dumping me at the Grub rescue command (I have KVM access). When I try to run this command:

insmod normal

The error message I get is:

error: file '/grub/i386-pc/crypto.mod' not found.

Please note that I do not have physical access to the server, so I am unable to use a live CD. Any other ideas how I can get this to boot?

  • Try to place crypto.mod into /grub/i386-pc. – Star OS Dec 7 '15 at 11:38
