install problems

Have uninstalled DSL & partitioned my hard disk,Bios has been changed to run from CD.Unfortunately no CD`s are recognised,it freezes at the "booting from CD" message.the CD`s are all free from variuos magazines and are different distros they all do the same.any help would be appreciated,many thanks in advance john wayne

I know it's a long shot,

I know it's a long shot, but most magazine CD's are now DVD's, are you trying to play them in a CD player?cheersFredd
