I have VirtualBox-4.1 installed in Ubuntu 10.04 with a .vdi running Xubuntu 12.04. Recently, a Grub update for Xubuntu 12.04 to Grub2.x, broke it with the following explanation: error: ELF header smaller than expected grub rescue _ Is there an easy fix for this? I could reinstall, but I tweaked Xubuntu 12.04 to my liking, and don't want to re-install a new .vdi. Unfortunately, I didn't make a snapshot of it. Google results, have been over my head. Thanks.
