Incredible frustration at Grub/linux!

Do you have a separate /boot partition?

GRUB uses the /boot/grub/menu.lst configuration file to build the boot 
menu.  Open the file with some text editor, and find the entry for your 
kernel.  It should look something like:

title Red Hat Linux (2.4.20-24.9)
         kernel /vmlinuz-2.4.20-24.9 root=/dev/hda6
         initrd /initrd-2.4.20-24.9.img

make sure you are editting the right section for your current kernel. 
Actually, you should copy+paste the section and change the title (stuff 
in the "()") to something like "test" so if anything goes wrong you have 
your origional settings.

Next, change the root(hdx,x) entry so it points to the partition 
containing your kernel.  If you have a boot partition, then you probably 
don't need to change this (unless you are also trying to backup and test 
it), but otherwise it should point to your new root partition.  The 
first x is the IDE physical drive ID (0->hda; although there are some 
strange issues that may change these mappings).  The second x is the 
partition number.

Change the root= in the "kernel" line to your new root partition.  It is 
probably set to "LABEL=/" which will always point to your origional 
partition.  Try replacing it with the real device (/dev/hdxx).

Reboot and select the new entry at the prompt.

If you encounter any more problems, can you please attach your menu.lst 
file and the output of:
# /sbin/fdisk -l

I hope this helps.
