Red Hat

Praveen,
Have attached few diagnostic files below
that show which partitions I have and whats installed where,
including the grub files for Red Hat, Ubuntu and Fedora.

I ran the script from Ubuntu
vinorda@vinsUbuntu:~/Downloads$ sudo bash ./boot_info_script055.sh
results contained in RESULTS.txt file also attached.
I have edited the results bit to make things more clearer.
NB You can't see menu entry for RH in Ubuntu cause after I updated grub
in Ubuntu, it lost RH entry.


I also ran "update-grub" from Ubuntu -
It finds Red Hat 9 and Fedora but doesn't create boot menu entries for Red Hat - why?

vinorda@vinsUbuntu:~/Desktop$ update-grub
/usr/sbin/grub-mkconfig: You must run this as root
vinorda@vinsUbuntu:~/Desktop$ sudo update-grub
[sudo] password for vinorda:

Also attached image of my partitions - captured from Partition magic. Actually I used XP Computer Management to create all partitions.

Have since updated Ubuntu grub menu entry for RH to correct /boot and / location.

menuentry "Red Hat Linux (2.4.20-8) (on /dev/sdb5)" {
insmod ext2
set root='(hd1,4)'
linux /vmlinuz-2.4.20-8 ro root=/dev/hdb7 hdc=ide-scsi
initrd /initrd-2.4.20-8.img
}
using exact same format as in RH grub.conf
still doesn't boot RH - grub says file not found.

I think problem is that Ubuntu and Fedora use grub2 where as RH uses old grub1.
I have to find way to updated RH grub to grub2 but not sure if I can do that if I can't boot into RH. I am able to mount RH partitions from Fedora and change RH /boot files - maybe thats one way I can upgrade RH grub from grub1 to grub2.
But not sure if that would help.

regards

Hi Vinorda,
I could see that your RedHat /boot is available under /dev/sdb5 (hoping its data has not been overwritten); Please try to mount the same as below:

Code:

mkdir /mnt/redhat;
mount -t ext3 /dev/sdb5 /mnt/redhat

You may use either Ubuntu or your Fedora-1 (preferably) to execute the above command.

Now copy that /mnt/redhat/grub/grub.conf and save the same somewhere as rehat9_grub.conf.

You now need to copy the same file from your fedora-10 (i.e. /boot/grub/grub.conf) and save that too somethis as fedora_grub.conf.

Now could you please post back here with there two files again?

The grub.conf for
RH, Ubuntu and Fedora are contained in the RESULTS.TXT file I sent earlier... about half way down..

BTW I used RH 9 installation CD to update boot loader on the mbr
(which in may case is on 1st HDD)...
now I can boot into Red Hat and my XP as before BUT can't boot into
Ubuntu and Fedora cause Red Hat menu doesn't contain these.

You see I had problems with Ubuntu and Fedora not being able to boot RH 9,
even after I edited Ubuntu and Fedora grub to create RH boot commands etc.
Now hopefully I can edit RH grub.conf to boot Buntu and Fedora.

But Buntu and Fedora use grub2. RH 9 uses grub0.97 (legacy).
So will take my chances.....

You shouldn't have run the RH9 installer. Rather I was planing to add RH-9 through fedora installation only. That's why I wanted the exact entries of RH-9 as per your system and that we could have got through mounting that volume only.

Atleast GRUB2 is anyways backward compatible with GRUB0.97; hence the approach I usually do (and was planning in your case) would have worked.
