For several years I have let the anaconda loader put the grub boot message in the spot for such things on /dev/hda/. Fine, a couple of years later I bought a much bigger hard drive and this Linux is on that. But Grub is still using /dev/hda/.
These are both Western Digital hard drives and I have had good luck with them. But the first to fail will be the oldest I expect. When that happens Grub will fail. This is a real hard thing to fix :-(
So I have a plan. First read "Info Grub" and see how to put a Grub boot in the boot section of /dev/hdb/. This I think is pretty simple. I can do this today. But how to cause the file /boot/grub/grub.conf to use this new boot point may be difficult.
Assuming this is possible I will let the list know. Karl
