Boot Problem

Would someone please be kind enough to help me or point me to 
someone/somewhere that can?


I have a system with Linux installed on it and when I boot it drops into 
a Grub> command prompt.


If I use the following command: configfile (hd1,3)/boot/grub/grub.cfg it 
proceeds to the grub menu and allows me to boot as normal.  I have been 
trying for several days to figure out why it always drops me into the 
grub prompt.  How can I tell it where the config file is such that it 
remembers it and stops dropping me into the prompt?


Thanks,


Keith
