    Let me add how to fix your grub problem. If your linux system is in 
/dev/sda2 then here is what you should do.

    Using a rescue disk just boot up to a prompt. There type grub. When 
it is up you do these two things:

# grub root (hd0,1)
# grub setup (hd0,1)
# grub quit

Now get out of the rescue mode and you should be able to boot up linux 
in the same old way.
