Ok, I will do what you advice. Just to make there is no
misunderstanding, I do not have any more the FC4 on the systeme but
only F8 (after multiple upgrade)

So grub-install will install grub into the bootloader, I need first to
convert the lilo.conf settings into a grub.conf settings. I have paste
and copy what it look good for me. Can you tell me if it look right
(sda1 => hd0,1) ? next, how do we know reboot will work, do we have a
way of testing the setup ?

Thanks,
Thomas
