 You don't actually need to re-install grub and in fact i've done that before 
and it didn't actually fix the problem. Grub does however have a command 
that is basically a fixmbr in windows jargon, but I can't remember off the 
top of my head what is was. Every time I've done that i've done it from the 
grub shell. The thing you get into when you just type in "#> grub". 
Basically man grub was my friend for a while. 

For the usb stick I would definitely run the command from the grub shell 
just to see if there are any nasty things done to the USB stick like have 
the first block locked down for some strange reason or any number of strange 
tricky things. The fact that you tried to get your usb stick to boot and 
ended up hosing your hard drive leads me to believe that things were not 
happening the way you expected them to. Perhaps a good first step is to boot 
into the rescue cd and getting your USB to boot and get grub on it and then 
going from there. Perhaps even unpluging your hard drive to make 100% sure 
that nothing is writing to it. It's extreme but that was just the easiest 
way I found to not write to a drive when I didn't want to. Just my 2 cents.
