you need to mount /boot before you can read it properly do that then run:

read the tutorial section on recovering from what you have done.
It's in the GRUB howto section that I wrote.
Use Suse 10.1 and occasionally play with Kubuntu
Also have Windows 98SE and BeOS

boot to knoppix and create a grub floppy like so:
Creating a GRUB boot floppy
To create a GRUB boot floppy, you need to take the files `stage1' and `stage2' from the image directory, and write them to the first and the second block of the floppy disk, respectively.
Caution: This procedure will destroy any data currently stored on the floppy.
On a UNIX-like operating system, that is done with the following commands:
# cd /usr/share/grub/i386-pc
# dd if=stage1 of=/dev/fd0 bs=512 count=1
1+0 records in
1+0 records out
# dd if=stage2 of=/dev/fd0 bs=512 seek=1
153+1 records in
153+1 records out
at the command line example:
#root $BOOT PARTITION
Replace $BOOT PARTITION with your boot partition e.g. (hd0,3)
This should allow you to boot into redhat.
Once you have done this re-install grub to your mbr and all should be well.
GRUB how to can be found at http://www.mcc.ac.uk/grub/grub_toc.html#SEC_Contents
Good luck, and keep the grub floppy for any future problems - leaning how to manipulate the GRUB command line is a usefull skill.
