Error Message at boot mountall: error while loading shared libraries

i am running on Ubuntu Linux 2.6.31-22 Generic !!

Sounds bad. It seems that the system cannot mount the partitions because one of the files on your system is corrupted.

Here is what I would do:
-use a liveCD, boot on it, and check the hard drive for errors. Maybe there is a physical problem on your hard disk, so it's important to make sure if it's reliable or not
-if the disk is fine, then I would use a LiveCD with the same version as your current system to copy/paste the missing file on your harddisk. Then try to reboot. Maybe it could fix the problem if this file is the only corrupted one of course ! However, if it's not the only one, you could try to repeat the process.
-if it's too complicated with many corrupted file or a failing hard disk, you can use the LiveCD to backup your documents and then reinstall the system.

Okay what if i do not have the live CD, with the boot on it.
or any live cd, can i go too this web site and download it ,
or download a new version of Ubuntu Linix, and put it on my computer ??

and if so what one should i download? how do i find it ?

Thank you for all your help.

You can find the packages online I think, but you still have to extract the file from it.

Maybe it's not worth the trouble: if your computer is recent enough (let's say 4 to 5 years old), you can install the new version, it's out since this Sunday... Go to Ubuntu.com, it offers the download on the homepage.

okay sounds great , but can i download the new version , onto a cd-rom disk , because i can not download it directly on my computer because of the error message,

And how do i pass the error message , so that i can download it , too my computer,
thank you

Your problem seems serious, you should use another computer to download the CD and burn it if you can. Anybody can help you ?

yes thats what i thuoght !!

But when i go too put the cd in my computer, will it reject it, because of the error message ,
or i there a way too by pass it, so i can let my computer down load it. or will it just download it when i put it in my hard drive?

And i was reading something , can i just go into the system and erase everything, boot it totaly , start brand new
too like factor settings ??

thank you !!

To burn the CD with the installer, you need a computer with a working system :) So you need a Windows XP, Mac OSX, Ubuntu, whatever, but working fine, with internet access :) Then you download the ISO image, and use a burning software to burn the CD (or copy on a USB stick, that's also possible).

You need to do that to have a CD or USB stick to reinstall the system. I really think it's the easiest solution. It could be very complicated to fix your current one, there is no such option as "resert to factory settings", especially when y ou cannot even boot the system :) So the CD is the answer, burn it on another computer, then use it to do a clean install, that should work much better.

Also, remember that when you start with the liveCD, you can check if the harddrive has a problem. I think you should do it, because if your hard drive has a problem, you need to know it and replace it. The disk testing software is in "System>administration".
