This seems to be where /dev/root comes from. And my kernel can't find
it for some reason.

mount --ro -t ext3 /dev/root /sysroot

There is a point in the boot sequence where the bios-loaded kernel
trades the initrd RAM disk image (also bios loaded) for the real root
partion mount point. Several things can go wrong here. Grub may have
told the kernel to look in the wrong place for the root file system,
the file system might be unreadable, or you may have moved the system
onto a machine with a different type of disk controller that needs a
different driver module included on the initrd. The main reason you
need the initrd is to load drivers for the root filesystem if they
aren't compiled into the kernel but it will only include ones for the
the machine where the system was originally installed. If you can
access the disk, somewhere in the boot messages you should see it
detecting the device and partitions. If you don't see that, the
kernel can't see the disk and you'll have to rebuild the initrd with
the right module.
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 :-)
If your rescue boot mounts the system drives and suggests a chroot
command, do that, then add the right alias command to /etc/modprobe.conf
(will depend on hardware) and then run mkinitrd.
