what command are you issuing when you got this error?

it seems you missed the initrd file option passing to grub while booting. or initrd is corrupted.

There is no inittab in ubuntu, as it's using upstart. You can boot from live-cd, work in the live CD and mount the file systems manually then fix things:

Code:

mount /dev/"root-filesystem" /mnt/
usually root-filesystem is something like "sda5" or something similar.

mount --bind /dev /mnt/dev
mount --bind /dev/pts /mnt/dev/pts
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt

then in the chroot you update or create a new initrd:

update-initramfs -u -k "kernel-version"
or
update-initramfs -c -k "kernel-version"

after this exit chroot with logout or Ctrl+D

umount /mnt/dev/pts
umount /mnt/dev
umount /mnt/proc
umount /mnt/sys
umount /mnt

and reboot

This way should fix your initrd, but you have to know which is your root-filesystem and the kernel version. If in case you have /usr and/or /boot as a separate partition you will need to mount that too.
