I've got a problem. Grub loads, but only into commandline mode.

If I issue configfile /boot/grub/grub.conf at the comand line then my boot menu shows up. The entries in the boot menu work (well, the first and third ones do, anyway).

This is my grub.conf, if that makes a difference:
----------------------------------------------------------------------------------------------------------------------------------------------
# Note that you do not have to rerun grub after making changes to this file
#boot=/dev/hda
default=0
timeout=10
title Knoppix (2.4.24)
root (hd2,2)
kernel /boot/vmlinuz-2.4.24-xfs ro root=/dev/hde3
initrd /boot/System.map-2.4.24-xfs
title Knoppix Biv (2.4.42)
root (hd2,2)
kernel /boot/bzImage-biv-2.4.42 ro root=/dev/hde3
initrd /boot/System.map
title Windows 2000
rootnoverify (hd0,0)
chainloader +1

Haven't even had a chance to figure out why Knoppix Biv doesn't start. Sigh.

Did I incorrectly install Grub?

Thanks, in advance,
