How to add to grub?

[Bob Goodwin]

I installed F-10 on this computer but in creating grub the installer 
ignored the existing F-8 on drive /dev/sda.  I thought it would present 
me with a grub screen for selection of the other system but it didn't 
happen.  I don't actually need or want F8 but if I can make it work, 
since it is already there, then I should be able to replace it with F0 
or even Centos.  I have a genealogy program [Ftree] that seg faults with 
F-10 on both computers.

I began making a modified grub but when I got down to the last section I 
find that the F8 drive contains no /boot/vmlinuz - ****.  It does 
however contain kernel rpm files in the yum cache. 

Can someone tell me how to procede?  Suggestions, forget it maybe?

    I added a line to fstab so that I can see the files on the 80g drive
    /dev/sda.
