Ubuntu GRUB Problem.


I have installed the following operating systems on my comp in the following order

1. Windows XP

2. Cent OS

3. Slackware

4. Ubuntu.

Now the thing is , before installing Ubuntu, All the other were working fine.

The problem lies in the GRUB.

CENT OS is being mounted as READ ONLY.

SO, I can't boot into Cent OS properly. I mean, I can start the Cent OS. But the boot process hangs badly at the Sysklogger daemon being started.

How can I get around this Issue?

I hope you guys have understood my problem.

Hello!

Could you post the section from grub.conf about CentOS here?

I edit /boot/grub/menu.lst to password protect the root prompt. Take a look there.

menu.lst


Code:
# This entry automatically added by the Debian installer for an existing
# linux installation on /dev/hda8.
title		Slackware 10.1 (on /dev/hda8)
root		(hd0,7)
kernel		/boot/vmlinuz root=/dev/hda8 ro 
savedefault
boot


# This entry automatically added by the Debian installer for an existing
# linux installation on /dev/hda6.
title		CentOS 4.0 (2.6.9-5.0.3.EL) (on /dev/hda6)
root		(hd0,5)
kernel		/boot/vmlinuz-2.6.9-5.0.3.EL ro  
initrd		/boot/initrd-2.6.9-5.0.3.EL.img
savedefault
boot
I don't see anything unusual in that.

Slackware too, boots in an unusual way. I don't know why!

I am getting Kernel panics with Slackware.
Cent OS just doesn't boot.

Everything was working fine, before Ubuntu was installed.


This was my previous menu.lst. I have restored it back now. But still no luck.

Code:
title		Ubuntu, kernel 2.6.10-5-386 
root		(hd0,6)
kernel		/boot/vmlinuz-2.6.10-5-386 root=/dev/hda7 ro quiet splash
initrd		/boot/initrd.img-2.6.10-5-386
savedefault
boot

title		Ubuntu, kernel 2.6.10-5-386 (recovery mode)
root		(hd0,6)
kernel		/boot/vmlinuz-2.6.10-5-386 root=/dev/hda7 ro single
initrd		/boot/initrd.img-2.6.10-5-386
savedefault
boot

title		Ubuntu, kernel memtest86+ 
root		(hd0,6)
kernel		/boot/memtest86+.bin  
savedefault
boot

### END DEBIAN AUTOMAGIC KERNELS LIST

In grub, ro means read-only or root?

sorry, I come from slack, I don't know how grub work yet.

All I know is that if the hard disk order is messed, that partition would not boot anymore. e.g. hda2 -> hda3

Maybe that was the reason for the errors that I was getting.

But frustrated, I formatted, and installed Ubuntu finally.
