I was fooling around with my grub.conf file and I 
thought I'd try "hide(hd0,3)" which is of course my 
extended partition, which includes /boot (in the 8th 
partition) and /boot/grub/grub.conf
So when I rebooted I got a Grub Error 22 (No such 
partition) in stage 2.
Is there some way for me to get into the grub shell and 
easily undo this (with a unhide(hd0,3) command perhaps)?

Anything else I might try to recover my extended 
partition? 
(I have the important stuff backed up if I need to start 
from scratch).

Thanks,
Mike Nixon
