ubuntu mount fails after update to 14.4

Asked by Alan Lilly

I updated Ubuntu and it no longer works. I received the following:

mount : mounting/dev on/loop0 on/root failed : invalid argument
mount : mounting/sys on/root/sys failed : No such file or directory
mount : mounting/proc on/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 shell(ash)
Enter 'help' for a list of built-in commands
(initramfs)

I have a dual boot machine and I wish to restore Ubuntu to its operational state. I boot off of the Windows loader (preferred).

I have created the new Ubuntu image for 14.4.

What OS is the other one on your system?
Is your Ubuntu system a "wubi" installation inside Windows?
How did you initiate the update of your Ubuntu system?
Which Ubuntu version did you have before the attempted update?

Sorry that I was long in getting back. The Holiday schedule has me running all over the place.

I have Windows 7 Home Premium on my machine.

I boot into either system at startup with no other means of moving between the two.

I initiated the update from within Ubuntu.

After checking back into my email archives, I found this information: Ubuntu 9.04 - Install/Live CD (PC)

Since I have the Ubuntu 14.4 CD and I didn't have any data within Ubuntu that I need to preserve, I would appreciate a tutorial that would guide me through the install within the existing partitions.

Thank you

Can you try the following:

insert the Ubuntu 14.04 DVD into your computer, reboot the system and instruct the BIOS to boot from the DVD.
When asked select "Try Ubuntu without installing".
When you have reached the Ubuntu desktop, open a terminal and issue the command

sudo fdisk -l

and copy/paste all output into this question document.

This should reveal the details about size and layout of your hard disk(s) and disk partitions.

Ok, this seems to be a Wubi installation. To confirm this, please boot into Windows and check whether you have:

1. C:\ubuntu and C:\wubildr* files/directories
2. In the Add/remove dialog of the Windows control panel and entry named "Ubuntu".
