i have a system that had fedora core 3 running perfectly fine..then i tried to install gentoo along side it. now whenever i boot up the computer i get the grub> prompt but no menu. if i manually boot it like this

root (hd0,1)
configfile /grub/grub.conf

then it works fine i have tried

grub> setup (hd0)

doesnt work
and i have tried using grub install but to no avail...can someone help me?
if you think you need to see any config files let me know

Do
and explain where's your /boot partition, and both / partition of Fedora 3 and Gentoo.

theres my disks

mmmmmmmm if hda1 = (hd0,0) wouldn't hdb1 = (hd1,0)

and so on do u get it?

Basically I'd reckon you shouldn't have run grub at all from Gentoo - merely copied the kernel/System.map/config to your boot partition, and updated grub.conf.

So, I'd go back and boot the FC3 CD and reinstall grub from recovery.
Then do as I suggested above, and add an entry for Gentoo to the grub.conf.

Then you should be right to go.

The reason I suggest it this way, is that the installer for FC? will likely toss a fit when you next upgrade it if you try to leave a Gentoo generated grub in place.
Probably not worth the grief. Gentoo gives you the option to work it all out - Fedora probably won't.

true I forgot about FDC since it is a RPM distro it could have conflicts with it interesting point syg00, I totally forgot that he install grub from fedora. U did install grub from Fedora correct? or did u install it using Gentoo?

actually i just fixed my problem i just had to specify the configfile when i did grub> setup thanks for your help tho guys
