Hi Guy's,

Here is my problem.

I have 2 x 160G hard-drives.
Drive 1 installed Fedora 11
Drive 2 installed Ubuntu 9.04

GRUB displays only Fedora or Ubuntu seperately. How do I add Ubuntu to the fedora GRUB?

I have read up a lot and my head is spinning, I need someone to explain in easy step-by-step terms how to do this.

I got hold of cat /etc/fstab and ran in terminal this is what I got.

Fedora:
# /etc/fstab

# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or vol_id(8) for more info
#
UUID=827baf3c-631d-4922-b960-b5e814df5ef8 /boot ext3 defaults 1 2
/dev/mapper/vg_fedora00-lv_root / ext4 defaults 1 1
/dev/mapper/vg_fedora-lv_swap swap swap defaults 0 0
/dev/mapper/vg_fedora00-lv_swap swap swap defaults 0 0
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts defaults 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0



Ubuntu:
# /etc/fstab: static file system information.

# Use 'vol_id --uuid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# / was on /dev/sda1 during installation
UUID=2aa405a1-77f2-4e98-af28-e7c49d501dc4 / ext3 relatime,errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
UUID=e7ccafaf-5e45-430a-a6f5-3793747d854a none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0

Thanks in advance for the clever people who will be able to help me ;)
 
I'm gonna assume you're working from Fedora.

On your Ubuntu partition look at the file /boot/grub/menu.lst. Look for any lines that look like this (they don't have to be exact, just similar):

title Ubuntu 9.04
root (hd0,0)
kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=291da951-fd1f-4709-948f-07aecbea4223 ro quiet splash
initrd /boot/initrd.img-2.6.28-11-generic
savedefault
boot

You need to append that to /boot/grub/menu.list in Fedora.

Also note that since Ubuntu will now be running of the second drive make sure you change "root (hd0,0)" to "root (hd1,0)".
 
Thks concentricpuddle,

Found this, let me know if it is right please.

Yip. You don't need to change any root (hd0,0) since it seems Ubuntu is just using UUID's (a unique marker for your hard drive).

So just add what you pasted to /boot/grub/menu.list on the Fedora partition and you should be fine.

In case you're wondering

is for running Ubuntu as normal while

is sorta like safe-mode for Windows, but you just get a console to work with (once you know what you're doing it's quite a joy to have).

Anyway, just holler if anything's amiss.

Thanks.

Now I just need to figure out how to open the /boot/grub/menu.lst. in Fedora as root and edit.
 
Nearly there.....

I see Fedora and Ubuntu in Grub menu, when I select Ubuntu I get "Error 15 file not found" ?

This is what the menu file looks like now:

# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

Damn, I hate it when my advice doesn't work. Anyways, just change

for both Ubuntu headers, so that your menu.list looks like this.
