the situation is first i installed RHEL 5 then Fedora core 7 ,then to boot both them have to edit the grub.conf.
now if i want to delete Fedora core 7 and only want to use the first one (RHEL5)then what should i do with grub.conf
this grub.conf from fedora core 7
Code:
# 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 (hd0,9)
# kernel /boot/vmlinuz-version ro root=/dev/hda10
# initrd /boot/initrd-version.img
#boot=/dev/hda
