So Windows runs fine when you boot your system without the Linux boot
disk, right?  And when you put the boot disk in, you get the boot error,
right?

Did you remake the boot disk when you upgraded RedHat?  You were supposed
to.

Yep:

   1. Run `linux rescue` from the CD.  You should get to the shell prompt.
   2. Mount the hard drive's root.  Assuming it's /dev/hda2, and it's
      ext2, type:

         mkdir /mnt/hdroot
         mount -t ext2 /dev/hda2 /mnt/hdroot

   3. Chroot to that directory:

         chroot /mnt/hdroot

   4. Run mkbootdisk with proper arguments.  I haven't run mkbootdisk
      manually before, but from the manpage I guess it's something like:

         mkbootdisk /boot/<kernel_filename>

      There are some other options you can pass to mkbootdisk depending
      on the situation.
