Dual boot Ubuntu and Fedora

[uniquerockrz]

I had Ubuntu 10.10. Now in the free space remaining in my hard disk, I installed Fedora 15. But unfortunately, Fedora failed to detect ubuntu. Now when I start my computer, grub automatically loads fedora and also doesnt display the boot menu. How can I boot ubuntu and let the grub display a menu of operating system choices? My /etc/grub.conf file in fedora is as follows:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,0)
#          kernel /boot/vmlinuz-version ro root=/dev/sda1
#          initrd /boot/initrd-[generic-]version.img
#boot=/dev/sda
default=0
timeout=0

Make these changes to the menu.
default=0
timeout=10 < --- Change this to 10 seconds instead of 0 seconds
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
hiddenmenu < --- Remove this line

Those 2 changes will give you a 10 second countdown before the default is booted and actually display a menu.

Adding Ubuntu could be tricky. It depends on, amongst other things, what partition it is installed to. I have Ubuntu installed on /dev/sd8 / (hd0,7) so my menu entry looks like this.

title	Ubuntu 11
	root (hd0,7)
	kernel /boot/grub/core.img

You could try to emulate that and see if it works.
