Add Fedora in the boot menu after installing Ubuntu 9.04

Posted by srinwantudey on May 17, 2009

This is a very common problem among the Ubuntu users who earlier have installed Fedora in their machine, doesn’t find any boot menu option to enter into Fedora system after a fresh Ubuntu installation. You just need to do some basic changes in your configuration.
First you need to know the partition where the Fedora has been installed. To get this, open up your terminal and give command blkid there. You will get something like this:

neo@neo-laptop:~$ blkid
/dev/sda1: UUID=”547C6BE77C6BC27A” LABEL=”Lenovo Systems” TYPE=”ntfs”
/dev/sda3: LABEL=”/boot” UUID=”783a0035-4782-4382-9782-2ad4f8ed982f” SEC_TYPE=”ext2″ TYPE=”ext3″
/dev/sda4: UUID=”HwL4aL-8Lh3-MjAP-1k7Q-Yfv8-OLi1-1GStKZ” TYPE=”lvm2pv”
/dev/sda5: UUID=”0029482318BE6784″ LABEL=”Entertainments” TYPE=”ntfs”
/dev/sda6: UUID=”4AE13D6C2CD672AE” LABEL=”Work Station” TYPE=”ntfs”
/dev/sda7: UUID=”69525F9016496DF1″ LABEL=”Library” TYPE=”ntfs”
/dev/sda8: UUID=”5AF141BB26E901EB” LABEL=”Reserve” TYPE=”ntfs”
/dev/sda9: UUID=”ca774c9d-9bcb-475a-beae-8edd6aeaa30c” TYPE=”ext3″
/dev/sda10: TYPE=”swap” UUID=”95e3d02f-5984-42c8-9213-6a6174c47ff4″
neo@neo-laptop:~$

To get the list of all the logical volumes type lvdisplay in the terminal. If the command doesn’t work, install it by the commandapt-get install lvm2 as root. You possibly will get an output like the following:

root@neo-laptop:/home/neo# lvdisplay
— Logical volume —
LV Name                /dev/VolGroup00/LogVol00
VG Name                VolGroup00

Now you need to open the menu.lst files which controls the boot options. you can find that in /boot/grub location. Give command gedit /boot/grub/menu.lst as root to edit the menu.lst. You will find output like the following:

# menu.lst – See: grub(8), info grub, update-grub(8)
#            grub-install(8), grub-floppy(8),
#            grub-md5-crypt, /usr/share/doc/grub
#            and /usr/share/doc/grub-doc/.
## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify ‘saved’ instead of a number. In this case, the default entry
# is the entry saved with the command ‘savedefault’.
# WARNING: If you are using dmraid do not use ‘savedefault’ or your
# array will desync and will not let you boot your system.
default         0
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout         10
## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu
# Pretty colours
#color cyan/blue white/blue
## password [‘–md5’] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line)  and entries protected by the
# command ‘lock’
# e.g. password topsecret
#      password –md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
# password topsecret

You can find my updated menu.lst here: http://pastebin.com/f4c219592
You may need to change the kernel version and initrd image (2.6.27.5-117.fc10.i686) according to your Fedora version. Hope this will fix the issue.
