GRUB2 Doesn't find grub.cfg

[Vince Radice]

I would like to start using GRUB2. Seeing as I have several hd's in my 
pc and I can pick which one to boot from at start-up, I figured to put 
GRUB2 on a disk, boot from it until I get it working and then change the 
BIOS default.  3 hard drives - 2 IDE and 1 SATA.  IDE1 has WinXp, IDE2 
is data, SATA1 has 2 partitions - 10 gb data, 110 gb Fedora 12.  IDE1 
has GRUB Legacy loaded (this is current boot drive).  I use this to boot 
Fedora or XP.  I have installed GRUB2 on SATA1 and configured the 
grub.cfg file.  The config file is  /boot/grub/grub.cfg.  If I boot 
using SATA1, I get the GRUB command line interface.  How do I tell GRUB2 
to get the correct configuration file automatically?  Manually?

Thank you,
