My desktop pc gives the following error when trying to install from a cd:

Kernel requires a 86-64 cpu only detected a i686 cpu unable to boot

My pc is a Medion, 160GB hard drive, Pentium 4 processor, 512MB memory. I'm installing Ubuntu 12.04 from the (complete manual magazine).

Here is the link for Ubuntu 12.04.1 LTS 32bit – NikTh Dec 31 '12 at 13:33

You appear to be trying to run an amd64 (64 bits) build on a 32-bits PC. Download an i386 (32 bits) CD image instead from and make sure to select "32 bits" as the flavour.

The CD you have there will run fine on more recent hardware, though.
