I had the same message when I pointed GRUB to the uncompressed image of my 
newly compiled kernel.  Can't quite see how that would apply to your old RH 
7.1, but I have found that installation programs tend to mess up when you 
declare that you don't want any bootloader installed at all.  Suggest you 
boot from a recovery CD and have a look at the statements in GRUB's menu.lst 

Alternatively, a successful boot can often be achieved via tab-completion at 
the GRUB command line, if you have a floppy or CD that boots GRUB.
