After Installing BT I cant boot to Fedora... HELP

[Nabaachy]

Hi
Yesterday I installed back Track to my HDD. But after that I cannot boot into Fedora. I have fedora 7 and it uses grub to load it. After installing BT I found out that it has installed LILO with it.

In My HDD I have 2 partitions and a swap partition. I installed Fedora to hda1 and BT to hda 3. Hda 2 is the swap. so, heres my fdisk -l and LILO.conf.

I need your guys help desperately.....................

By the way, I started using Linux early this year and I got a lot of support to my problems from this forum, and I really appreciate you guys for what you are doing for the Linux community.

Cheers!

Hi !

Either add an entry of Fedora in Lilo OR re-install GRUB and add an entry of BT in GRUB.

So, what do you prefer? GRUB or Lilo?

[Nabaachy]

Hi devils_Casper,thanks for replying.

I think Grub is better right? what is your opinion?

which ever way that is better will do.

[devils casper]

I prefer GRUB only.
Boot up from Fedora 7 Installation CD/DVD and select 'repair/rescue mode'. I dont remember exact entry. This will drop you at shell prompt after asking a few questions.
Execute this

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

* If you have SATA disk, replace hda with sda.
Reboot machine. GRUB Menu will appear on Startup. Boot up Fedora, log in as root and open /boot/grub/grub.conf file.
Add this code at the end of file

title BT
    root (hd0,2)
    kernel  /boot/vmlinuz root=/dev/hda3  ro
    initrd    /boot/splash.initrd

Save file and reboot.

IT WORKED!!!!! U R the man!!!!

So like this i can triple boot too right? I have to edit only the "(hda0,2)" to "(hd0,3) and "root=/dev/hda3" to its respective partion....is it?

Thank U VVV Much, I really appriciate it.

So like this i can triple boot too right? I have to edit only the "(hda0,2)" to "(hd0,3) and "root=/dev/hda3" to its respective partion....is it?

Correct. You can setup triple/multi boot exactly same way.

Glad to help you.


Edit:

I prefer chainloading and I would suggest you to use that only.
Let say, you are installing new distro in /dev/hda4. Add this code in Fedora's grub.conf file

title <new_distro>
    rootnoverify (hd0,3)
    chainloader +1

Install new distro in /dev/hda4 and select /dev/hda4 as install location of Boot Loader. It will install new distro's boot loader in boot sector of /dev/hda4.
You wont have to re-install Fedora's GRUB or do anything else. Fedora GRUB will chainload boot loader of new distro.

Thanks Again. Keep up the good work.

I don't know why Slack still use Lilo instead of grub and also there is no setup script during the installation of lilo to check and write configuration file for other operating system , i was expecting this will be implemented in the new release !

[devils casper]

Slack gives an option to install Lilo in Boot Sector but I have never chainloaded Lilo from GRUB so I dont know if that will work. 90% distros uses GRUB only and chainloading will work there.

HI!
today I re-installed fedora again to the same partition where it was before, after that I added the code below to enable to boot to backtrack. But I guess it was a mistake. I tried installing lilo and again installing grub. but the same error comes up.

THIS IS THE ERROR I GET

root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /boot/vmlinuz-2.6.21-1.3194.fc7 ro root=LABEL=/1 rhgb quiet

[Linux-initrd @ 0x1f511000, 0x2bdf7e bytes]
root (hda0,2)
Error 23: Error while parsing number

Press any key to continue....

When I press a button, it restarts again


************************************************** ***
This is the code that I added at the end of the grub.conf

title BT
root (hd0,2)
kernel /boot/vmlinuz root=/dev/hda3 ro
initrd /boot/splash.initrd
