1. I assume that "keernel" above is a typo in the email and does not
   appear in the real menu.lst file.

2. Make sure you have built RedBoot for GRUB startup, other versions
   of RedBoot will not boot from GRUB.

3. If GRUB is saying "file not found" then there is probably something
   wrong with the pathname. I'm not sure why you have put the
   redboot.elf file in the /boot/grub directory rather than the /boot
   directory. Also check that the disk/partition specifier is correct.

4. You might need to drop into the GRUB command line to try out
   various things to see what is going on.

5. Try booting from a floppy disk rather than the hard disk. That way
   you have total control over the contents of the disk. Once you have
   things working from a floppy, you should better understand what you
   need to do for the hard disk.


Apart from that, I cannot think of anything else to suggest.
