kernel removed -- please help

[Sandeep Shekhar Prasad]

I have done a really stupid thing!
I issued the following command 
rpm -e kernel-2.4.22-1.2179.nptl

and then rpm -i kernel*1.2174.nptl.*rpm

and then rebooted the comp 

I wanted to switch from 2179 to 2174 kernel (as I was facing graphical 
bootup problems after the upgrade)

Now the grub doesn't show the linux kernel to boot into fedora. I am not 
sure if 2174 kernel is installed or not.

I cannot re-install the system, as I have some files whose back-up I 
didn't make and I donot want to loose them

I have two partitions (made as default by anaconda - /boot and the other 
for entire sys)
I also have windows installed in another partition.

I tried to upgrade system through FC1 CD, but the upgrade/installation 
failed!!!


Help me, what can I do.
