    Just to be sure I didn't make a mistake, I pulled both
    drives out and checked. They are maxtor drives and
    the jumpers are shown on the drive. I had the
    old drive as slave and the new drive as master
    correctly.

    When you get to the lilo prompt,..... Never mind RH uses grub.
    I was going to say at the lilo prompt tell it where the root
    partition is located.

    linux root=/dev/hdaX

    But RH uses grub so that won't help.
    Use the installation CD and boot into rescue mode. If you moved
    the drives position then you may need to edit grub.conf so it
    uses the right device.

    With Grub it's a little bit different. When the Grub boot loader screen is
    displayed, press the 'e' key. Use the arrow keys (down arrow) and
    highlight the line that begin's with kernel and press the 'e' key again.
    Change the 'root=LABEL/' section to 'root=/dev/hdaX' then press the Enter
    key. Finally press the 'b' key to boot with the temporary change.

    It might be a good idea to modify both /etc/fstab and /boot/grub/grub.conf
    to not use the LABEL=/X scheme.

    By default, Redhat uses labels instead of actual partition names
    in /etc/fstab, and the root partition is labeled "/". This causes
    confusion when you have two partitions with the same label.
    Try typing "linux root=/dev/hda1 init=/bin/sh" at the boot prompt.
    If that works, you should be able to edit /etc/fstab.

    Thanks a lot!

    I modified grub.conf and fstab by putting in the /dev instead of
    LABEL entries and it booted up just fine.
    I was able to mount the old drive just fine too.
