    Initrd has to be the problem Les. I have had the old hard drive on 
this new box and I was surprised that FC6 would boot up but F7 did what 
it has done all along. Now I did load a new F7 on the old hard drive and 
it booted up fine. So this info backs up my belief that initrd is the 
problem.

    I will now try and find out HowTo rebuild initrd from a Rescue cd :-)
