I have RHEL 3.0.

It is now booting from /dev/hdc.

I want it to boot from /dev/hda.

How can I change this.

cat grub.conf


# grub.conf generated by anaconda

#

# Note that you do not have to rerun grub after making changes to this file

# NOTICE:  You have a /boot partition.  This means that

#          all kernel and initrd paths are relative to /boot/, eg.

#          root (hd0,0)

#          kernel /vmlinuz-version ro root=/dev/hda3

#          initrd /initrd-version.img

#boot=/dev/hda
