triple booting

[blackpantha]

ok, i have a little predicament.

Windows Vista is my main partition. Then i have fedora core 9 and ubuntu 8.10.
Im using the bootloader that came with fedora core 9, but it doesn't seem to detect ubuntu.

How can i make ubuntu bootable from Grub?

Oddly enough I just installed Ubuntu 8.10 on my laptop, along side of Fedora 10 Beta, Vista and XP. You need to get the boot stanza from Ubuntu's /boot/grub/menu.lst and add it to Fedora's /boot/grub/menu.lst. That's what I did and now my boot options include Ubuntu. I did have some trouble though. Ubuntu would not boot after initially adding it to my boot menu. I needed to make some changes, namely removing the line that reads

uuid 81de0f1f-daee-40fa-b0cc-0d5e0636deab

and adding this line

root (hd0,4)  <-- This will likely be different for your application.

Here's my current boot loader

default=0
timeout=30
splashimage=(hd0,5)/boot/grub/splash.xpm.gz
