How can I insert a disc which is already inserted? What am I missing?
Well, pretty simple... You don't have the correct disc "already" inserted.
Its a netinstall, hence the "net" so it needs the net. Its also only a couple hundred megs, so that should indicate it doesn't have the full tree available.
Grab the dvd if you want to install from the "same" disc, or choose another method.
As Joseph mention, if you downloaded the netinstall you should definitely use the net and not any CD/DVD installer. http://www.if-not-true-then-false.com/2011/centos-6-netinstall-network-insta...
This is a tutorial that will guide you through and points to the correct URL for package repositories and to the correct install.img file.
