That indicates that you have a grub.conf somewhere, which is loaded
by GRUB when you boot the system. "find / -name grub.conf" might find
it. Alternatively, in GRUB menu there's a command-line mode, which
you can enter with key 'c' and then run "find /boot/grub.conf" or
"find /grub.conf" to look for common locations of that file. If it
finds it, the partition is printed.

Why not? What error do you get? It would fail to add it to the apparently
non-existant grub.conf, but it would install the files.

default=0

#splashimage=(hd0,0)/grub/splash.xpm.gz
title RHEL3
    root (hd0,0)
    kernel /vmlinuz-VERSION ro root=LABEL=/
    initrd /initrd-VERSION.img

This is a template. (hd0,0) is /dev/hda1, your /boot partition.  You would
need to substitute VERSION with your most recent kernel version, also for
the generated initrd, and make sure that the / (root) partition has the
correct partition label. Run e.g. "e2label /dev/hda2" to find out. Else
specify the partition directly: root=/dev/hda2  (substitute hda2 accordingly)

In order to delete entries from your current boot loader menu, you must
find the grub.conf which is loaded. It is a file on your file-system,
provided that you use GRUB. Or did you install LILO at some point?
