Ubuntu

Just upgraded to Ubuntu 14.04 from 13.03 but system will not boot!

Asked by Todd

The screen says:

udevadm trigger is not permitted while udev is unconfigured.
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/dd1dad95-9bd3-429e-8e94-3f1d49da20e7 does not exist.
Dropping to a shell!

Busybox v1.21.1 (Ubuntu 1:1.21.0-1ubuntu1) built-in shell (ash)
Enter 'help' for a list of built-in commands.

Did you upgrade from 13.04 to 13.10 to then to 14.04? You can't upgrade from 13.04 straight to 14.04.

How did you try to upgrade?

If you have good backups I'd recommend a fresh install overwriting the the existing one. Make your install media USB or DVD boot from that and tell it to replace the existing Ubuntu.

If you don't have good backups you can boot from the install media select "Try without installing" and backup your data first then install fresh.
