Please, I have installed UBUNTU 14.04 on my netbook, that already had UBUNTU 12.04. When the up grade was completed, and after the restart, appears the following mesagge:

mount: mounting /dev/loop0 on /root failed: Invalid argumento mount:
mounting /dev on /root/dev failed: No such file or directory mount:
mounting /sys on /root/sys failed: No such file or directory mount:
mounting proc on /root/proc failed: No such file or directory Target
filesystem doesn't have requested /sbin/init. No init found. Try passing
init= bootarg.


BusyBox v1.21.1 (Ubuntu 1:1.21.0-1ubuntu1) built in suelo (así) Entre  'help' for a list of built-in commands

What can I do?

Try the following:

Boot from the Ubuntu Live CD and open a Terminal

Run sudo fdisk -l to get the device name. You'll get something like:

Disk /dev/sda: 250.1 GB, 250059350016 bytes 
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: **********

Device Boot Start End Blocks Id System
/dev/sda1 * 1 30238 242886703+ 83 Linux
/dev/sda2 30239 30401 1309297+ 5 Extended
/dev/sda5 30239 30401 1309266 82 Linux swap / Solaris

In this case, Ubuntu is installed in /dev/sda1. So type:

sudo fsck /dev/sda1

Restart the system and boot normally.

The mount: mounting /dev/loop0 on /root failed suggests this was originally a Wubi installation, in which Linux is stored within a large file on your Windows system. This would mean you accessed Linux from the Windows Boot Manager. This is no longer officially supported.

See Can't boot Wubi after upgrading to 14.04 from 12.04: "Target filesystem doesn't have requested /sbin/init" for workarounds to boot Linux.

In the longer term, however, it would be best to make a fresh installation in which Windows and Linux are on separate parts of the disk.
