Installed fedora, lost access to ubuntu

[liam.lah]

Hey guys i have a problem

I have been running Ubuntu 9.04 from a 320gb external hard drive, i have set the boot menu so if it is plugged in my computer will automatically boot ubuntu, and if not it goes straight to vista.

Tonight i tried to dual boot the external hard drive with fedora 11, when i installed it, i chose to shrink the current size down 100gb to fit fedora (had plenty of space), but now when i boot with the external hard drive plugged in, i am taken straight to fedora 11, with no boot menu allowing me to choose which distro i want.

Is there a way i can go through fedora and edit the grub so i once again have access to ubuntu?

Cheers.

Edit Fedora's grub menu (/boot/grub/grub.conf, if I'm not mistaken) and add Ubuntu. You should be able to copy the relevant text from Ubuntu's /boot/grub/menu.lst and paste it into Fedora's grub.conf.

Forgive me for i am new to linux, but i can't access the grub.conf, even if i try to access it in the terminal as root it says permission denied, i can access ubuntu's menu.list fine though.

i have managed to access grub.conf with


su -c "vi /boot/grub/grub.conf"

but i have no idea what to do with it, here is the menu.lst from fedora, they are very different. When i boot the computer it goes straight to fedora, if i choose "other" it says bootmngr doesnt exist press alt+ctrl+delete to restart

# 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)

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=279f31e3-c3b2-4e0e-8bfe-22dd1424e14b ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=279f31e3-c3b2-4e0e-8bfe-22dd1424e14b

## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

## specify if running in Xen domU or have grub detect automatically
## update-grub will ignore non-xen kernels when running in domU and vice versa
## e.g. indomU=detect
## indomU=true
## indomU=false
# indomU=detect

## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false
