Booting Problem after removing old Kernels
 

I need help to recover access to Ubuntu 14.04. I believe that I have deleted a file or files when removing old kernels to ensure that I didn't run out of space in my boot partition.

After removing the old kernels, I checked with `uname -r` that I still had the current kernel, which was present. After rebooting which brought up the Ubuntu logo, the computer did not continue through to a complete launch but dropped into a shell. I tried to use the recovery option on attempting to reboot and received the following information, after a long list of actions performed, and I haven't any idea what to do next.

Screen Printout

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/mapper/xubuntu—vg-root does not exist. Dropping to a shell!

Busybox v1.21.1 (Ubuntu 1:1.21.0-1ubuntu1) built-in shell (ash)

(initramfs)

After a suggestion I ran boot repair, from a CD and tried the boot repair option to "fix common problems", which had no effect, as the message when attempting an Ubuntu reboot stayed the same.

On re-running the alternative option, in boot repair, after attempting the "common problems fix" option, boot repair came up with the following URL http://paste.ubuntu.com/10816487.

Could someone please interpret the result and suggest a course of action.

Many thanks for any anticipated help

How did you remove it? With apt-get autoclean? One way to restore your kernel is to boot to a live CD and chroot to you OS. Then you can apt-get install the kernel again. Checking the current runtime for validation is not a good test because when linux loads into memory it doesn't prevent you from overwriting or deleting libraries from your runtime. This is why upgrades work so well.
