Ubuntu Boot Error — Missing modules (cat /proc/modules; ls /dev)

Boot from (hd0,0) ext3 5108701a-641d-43b182eb-aeb6da348d62
Starting up …
Loading, please wait…
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough ?)
- Check root = (did the system wait for the right device ?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/5108701a-641d-43b182eb-aeb6da348d62 does not
exist . Dropping to a shell!

Busybox v1.10.2 (Ubuntu 1:1.10.2-2ubuntu7) built-in shell (ash)

    Choose Safemode then you can update your packages. This is what worked for me running 10.04.1. It corrected the dreaded message about the “Missing models..”.
