Thread: Dual boot problem: RHEL 5.4 and Ubuntu 10.04

hi,

installed redhat enterprise linux 5.4 on pc.

partitions:
/dev/sda1 - /boot
/dev/sda3 - /
/dev/sda7 - swap

rhel config file located in /boot/grub/grub.conf & grub.conf file contains:

# grub.conf generated anaconda
#
# note not have rerun grub after making changes file
# notice: have /boot partition. means that
# kernel , initrd paths relative /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sda3
# initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title red hat enterprise linux server (2.6.18-164.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-164.el5 ro root=label=/ rhgb quiet
initrd /initrd-2.6.18-164.el5.img
title other
rootnoverify (hd0,4)
chainloader +1

then, installed ubuntu 10.04 choosing option install alongside of rhel

partitions:
/dev/sda8 - ext4
/dev/sda9 - swap

ubuntu 10.04 config file located in /boot/grub/grub.cfg & contains:

now, ubuntu startup menu not listing rhel menu entry , not able boot rhel.
pls me fix issue....

have tried , may want download lvm2 package first:

code:

sudo update-grub

if not download , run this:
boot info script courtesy of forum members meierfra & gert hulselmans
page instructions , download:
http://bootinfoscript.sourceforge.net/
paste contents of results.txt in new reply, highlight entire file , click on # in edit panel(code tags) make easier read.
or can generate tags first pressing # icon in new reply edit toolbar , paste contents between generated [ code] paste here [ /code] tags.
v60 has improved formating , requires code tags make legible. new version zip file have extract .sh run.
install these before running script:
able search lvm partitions if lvm2 package install
# ("apt-get install lvm2" in debian based distros)
# able search linux software raid partitions (md raids) if
# "mdadm" package installed.
sudo apt-get install mawk
