I have Ubuntu 11.10 64bit, and due to some installations via terminal, I lost many files in libc, and I can't repair, so, I need to reinstall Ubuntu 11.10. Please suggest an easy way to get Ubuntu 11.10 re-installed.

The best option is to install ubuntu from a usb or cd, you can download the iso from here ubuntu 11.10 64bits, burn the iso to a cd or usb, boot your computer with the cd or usb and install.

If the cd is an oficial one if note the iso file probaly it wasn't buurn fully on the cd. Try to burn it in a new cd –  MarcVal123 Mar 23 '13 at 11:20
    
If you burn it in a new cd it dosn't work try to burn it in a usb in windows an osX you can use deamon tools which is free for personal use this link to daemon-tools.cc/eng/downloads use DAEMON Tools Lite. –  MarcVal123 May 29 '13 at 17:59

Apart from all the answer here (correct) you might want to keep your home files and install Ubuntu on top of that.

Here you can find the most basic solution. Ask further if you need more help.
