unable to boot my system in Ubuntu server


Hi all

I have have an serious issue:

I have to haredisk in my system "sda" and "sdb"

in sda there are 2 OS installed which are RHEL5 and windoesXP

now I tryed to install Ubuntu and it got installed successfully.when I reboot my PC I found that my RedHat grub has got crashed.


I Again booted my system with RHEL5 DVD and entered in that rescue mode and and installed that Redhat grub (grub-install /dev/sda(#pwd /boot))
and when i see my system after getting reboot that Ubuntu grub was missing

can any one help me resolving this issue as my requirment is that i want my system to detect all that three OS which are installed..


Thanks and regards
KK

Post your /boot/grub/grub.conf file. Also give the following;

what your file system layout is for both linux distros.

IE
/ -/dev/sda1
swap /dev/sda2

or

/boot -/dev/sda1
/ - /dev/sda2
swap - /dev/sda3

How is your filesystem setup on your Ubuntu box? need to know what your boot partition and root partition are on.
