At this time F7 is booted and from that I used fdisk to find the
hard drive with F7 64 bit. As you can see it finds all the partitions as
/dev/sdf.
Command (m for help): p
Disk /dev/sdf: 160.0 GB, 160041885696 bytes

Note the last entry in df. That is /dev/sdf3 mounted on this computer
which is /dev/sda5.
I used fdisk and mount and df, three tools to show you what a hard
drive has. No one can say that /dev/sdf doesn't exist on my computer.
Some say the /dev/sdf3 is just a designator of a partition on a hard
drive. To this I say there is nothing else! I can mount the designator
and I discover it is a partition.
Next I must turn off this computer and come up with the rescue CD so
that neither computer is boot up. In this case with fdisk I found both
hard drives have changed. The hard drive that had been /dev/sdf is now
dev/sda. The one which had been /dev/sda is now /dev/sdb. How did this
happen?
Finally I boot up the computer on /dev/sdf3 and it becomes /dev/sda.
To my surprise I am booting it from /dev/sdb and not /dev/sdf. Here is
what my grub.conf looks like.

Now if it seems to you that I do not understand what is happening
then I got the message across.
