Default Problems Booting into Linux with Grub

Hi I am having trouble with Grub my system says that I need version
0.92-69 but the vdersion installed is 0.94-22.

I recently upgraded to KDE 3.3 and wondered if that had anything to do
with it.

I have tried uninstalling grub, rebooting and then reinstalling..... No
joy. I end up with a screen that displays the version,0.94 how much
memory neede (I think)
and finishes with the >grub as a prompt?

if I type boot, it says no kernal loaded. I am at my wits end, can
anyone please shed some light on this for me?

Probably not KDE. Did you upgrade kernels, move your disc partitions, or
something like that?

Note: comment inline. Caveat: I am not using SuSE.

As far as the prompt you are seeing when you boot up, if you manually
enter a kernel to load at this prompt, your kernel will load. Here is an
example (parameters are system dependant):

grub>root (hd0,0)
grub> kernel /boot/vmlinuz ro root=/dev/hda1
grub> boot

To fix you system so you don't have to manually enter the parameters
every time you boot, you will need to fix the boot menu
(/boot/grub/grub.conf or /boot/grub/menu.lst)

I don't know what you did to break the link to the menu, but you may have
done more damage when you unistalled grub. Perhaps, you have a backup of
the file /boot/grub/menu.lst or /boot/grub/grub.conf which can be
restored. Unfortunately, I don't know what the exact configuaraion file
that SuSE's grub uses. You can create a symbolic link to map both names
in any case. The specific menu entries are system dependant, and
that is the reason you may need the backup file- or you must be able to
recreate it from scratch.

Before you do a lot more damage to your system, perhaps you could study
the fine manual:
http://www.gnu.org/software/grub/man...ode/index.html

Starting the system is fundamental. This index shows quite some effort
has gone into keeping you from going to your wit's end:

Seems to me like you need to update your boot sector as your Grub files
appear to have been updated beyond what your Grub bootblock can cope with.
Get booted into Gentoo somehow. I suggest using your Gentoo live-CD and
chroot into Gentoo. Emerge sync and then emerge grub, mount your boot
partition then run grub from a root console. Rewrite grub to your boot
sector like you did when you first installed Gentoo.

Grub > root(hd0)
Grub > setup(hd0)

Replace hd0 with the disk that you boot from if different.

Which disro?
Was it working fine, before you upgraded?
What are the contents of your /boot/grub/grub.conf or /boot/grub/menu.lst?
