In /boot/grub/grub.conf you will probably have two different sections that looks something like this:

title Red Hat Linux (2.4.20-18.9)
root (hd0,1)
kernel /vmlinuz-2.4.20-18.9 ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.20-18.9.img

title Red Hat Linux (2.4.20-13.9)
root (hd0,1)
kernel /vmlinuz-2.4.20-13.9 ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.20-13.9.img

Each one represents a different kernel. If you don't want a kernel to show up at boot then you can erase(or better yet, comment out) all the lines in grub.conf . So in the example above, if you don't want the 2.4.20-13.9 kernel to show up you would change your grub.conf to this:

title Red Hat Linux (2.4.20-18.9)
root (hd0,1)
kernel /vmlinuz-2.4.20-18.9 ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.20-18.9.img

#title Red Hat Linux (2.4.20-13.9)
# root (hd0,1)
# kernel /vmlinuz-2.4.20-13.9 ro root=LABEL=/ hdc=ide-scsi
# initrd /initrd-2.4.20-13.9.img

Now when you reboot it won't show up anymore.

It's not as such a problem, it's for your convenience and to make it easy - if the new one causes problems you can boot to the old one.

Comment out the old one in /boot/grub/grub.conf if you don't want to see it or you can delete the entries and your old version in boot if you really want to.
