Recover Suse Grub

[divyashree]

I have installed XP 1st, then SUSE 11. Now I installed RHEL5 and during installation I only created /(root) partition bcoz while creating swap and /boot for redhat threw error.
And it says it is installing the /boot on /dev/sda.


Now my system is able to boot xp and redhat not suse. How will I recover suse grub menu ,so that I can boot all 3 OS.

fdisk -l
/dev/sda1   *           NTFS
/dev/sda2                NTFS
/dev/sda3                w95
/dev/sda4                 linux
/dev/sda5                 swap/solaris
/dev/sda6                 linux

Here Redhat is on /dev/sda4 and suse is in /dev/sda4 and the swap for suse is /dev/sda5

Here Redhat is on /dev/sda4 and suse is in /dev/sda4

In which partition did you install RHEL?

There is a problem with RedHat based installers. These installers don't detect other installed Linux distros. You have two options now.
1) Mount / partition of SuSe in RHEL, copy first title block ( first title, root, kernel and initrd lines ) from /boot/grub/menu.lst file and paste in /boot/grub/grub.conf file of RHEL. You don't have to re-install SuSe boot loader.

2) Re-install SuSe GRUB and copy title block of RHEL from its grub.conf file and paste in SuSe's menu.lst file.

If you want to re-install GRUB of SuSe, boot up from SuSe installation CD/DVD, select Recovery and execute this

chroot /mnt/sysimage
grub-install /dev/sda
exit
exit

First method is better than second, imho.

Sorry suse in /dev/sda6

As I suggested in last post, mount /dev/sda6 partition in RHEL and add an entry of SuSe in RHEL's GRUB Menu.

I have tried that adding in grub.conf ,from menu.lst of suse . But it doesnot boot and shows errors and prompt to reboot ,while booting from (hd0,5) .

Post the contents of both files here.
/boot/grub/grub.conf of RHEL and /boot/grub/menu.lst file of SuSe.
