I'm sorry about my last post when I think about it hd1 can be on the first controller because one ide controller is able to connect to 2 devices.

Regardless, the question that a posted still stands.

Is Centos on a different hard drive then Fedora or is it on the same one?

Sorry just another rookie mistake

i have a 200gb hdd
90gb allocated to windows (hdb1)

the remainder of the drive as follows

/boot for fedora (hdb2)
/home hdb3
hdb4 extended partition approx 78gb
/root for fedora 8gb hdb5
swap hdb6
hdb7 /boot for centos
hdb8 /root for centos

hope that helps. i also tried
title Centos
root (hd0,7)
kernel /vmlinuz-2-6-9-5.0.3 ro root=/dev/hdb8

however , i get the error " partition not found" so i guess im moving in the right direction. any suggestions

Now I am getting confused...too.

Snake do you have one hard drive or two hard drives...If you have one hard drive (which i think is the case) then your hard drive can not be hdb, it should be hda. This also seems to be the case if you see what LDZ420 pointed out.

All your kernel images point to hd0 which is the first hard drive (hda)...if they were hd1 then it would be hdb1.

Quote:
title Centos
root (hd0,7)
kernel /vmlinuz-2-6-9-5.0.3 ro root=/dev/hdb8
I think you are just missing the exact location of the kernel image. I believe it is wouldn't be in the root partition but in the /boot directory...

try this,

kernel /boot/vmlinuz-2-6-9-5.0.3 ro root/dev/hdb8

Edit: my apologies if i've given you wrong directions...

hey tux, thanks for your help. just to clear things up, i only have one drive. i have no idea why is hdb and not hda. come to think about it, its kinda of weird.
let me try your suggestion see if i get somewhere. hate to keep bothering you, but can you explain the paramaters needed in grub so that i can have a better understanding of what im doing.

below is my partition table, maybe this can help clear things a bit more. a brief summary of what i did, created a /boot partition for centos but did not install grub during installation. created a /root partition for centos. im sharing the /swap and /home so i did not created them during installation. by the way , i tried your last suggestion and im getting " file not found" .

e]# /sbin/fdisk -l

I think your problem is locating the kernel image...I suggest you look for it thoroughly...your grub is giving error "file not found" because you are pointing it to a place where there is no kernel image.

Tux,

And another question: Are you sure that the installation didn't create a seperate /boot partition? Have you run "fdisk -l" in FC3 to list your drives and partitions? ("fdisk" need to be run as root.)

Ok as you remember I am a rookie so I'm not sure if im on to something. But I looked at your previous post and something stuck out.

# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,1)
# kernel /vmlinuz-version ro root=/dev/hdb5
# initrd /initrd-version.img
#boot=/dev/hdb
/*drive that grub looks for kernel*/

/boot for fedora (hdb2)
/home hdb3
hdb4 extended partition approx 78gb
/root for fedora 8gb hdb5
swap hdb6
hdb7 /boot for centos
hdb8 /root for centos


Now I am not sure, so someone correct me if I am wrong. But maybe grub looks for boot partition finds /boot for fedora (hdb2) and then it says I canít find that Centos kernel.
Forget this. Iím out. And then gives you the "file not found"?

Iím not sure like I said Iím just a rookie. But maybe you should just have one boot partition and just have your kernel reside in there [/boot for fedora (hdb2)]?

// Side note
Another thing that came to mind is that you may have one hard drive but it is connected to the 2nd set of connectors. ( IDE cables have 2 connectors) this could be how you have one hard drive but Linux says that it is hdb and not had. Not sure but possible

thanks for the help, but i think i'll re-install centos again and allow grub to install this time around. i'll copy my current grub.conf file from fedora so i can add that info after i install centos again. hopefully this will work. i'll keep reading about grub though
