I am unable to perform a clean installation of Ubuntu 11.10

I am unable to perform a clean installation of Ubuntu 11.10 using the 32-bit or 64-bit installation CD on my dual boot computer as the screen breaks to a black background with a cursor without proceeding to the installation process. I am able to successfully complete the 64-bit installation process using a USB stick but on restarting the computer, it throws the following error message: “Error: invalid arch independent ELF magic”
Can anyone help me to resolve the issue?
