If you succeeded in mounting it, look in the old /boot (in other  
words, in /mnt/boot) If you don't recognize what you should be  
looking for after checking the manual entries, etc., ask again.

I've done this several times, including several times when I was  
fighting the old problem where you didn't want LVM handling volumes  
on more than one drive in a system. I don't know if that old  
limitation still exists, you'll want to check. (I probably want to  
check, too, but not today.)

The short answer to booting the old system is to remove the new  
drive. The long answer includes adding to the new grub configuration,  
new entries to either chain or directly boot the old system, but  
modifying the drive numbering appropriately. If you chain, I think  
you'll end up editing the old grub's configuration as well, because  
of the drive numbering problem.

Wish I had time to write a tutorial on it, but such do exist on the  
web. Some will be old and send you in the wrong direction, so look  
for something recent.
