Hi, I think you just have to manually edit the /boot/grub/grub.conf file (may be called menu.lst in some distros) and either add or change the line that says default=?
Here is an example grub.conf file:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.
# root (hd0,8)
# kernel /boot/vmlinuz-version ro root=/dev/hda9
# initrd /boot/initrd-version.img
#boot=/dev/hda
# By default boot the second entry
default=1
# Fallback to the first entry.
fallback 0
# Boot automatically after 2 minutes
timeout=120

from the console most people use vi. The command would be:

vi /boot/grub/grub.conf

From Gnome you could use gedit - a simple but good text editor.
From KDE try kedit - also a simple, nice text editor.
