my system has windowsXP and Linux enterprise redhat 3.0 . now i wanted to install another Linux distro RHEL AS4.0..(TRIPLE BOOT)
but when i started the installation..the bootloader of RHEL AS version is not recognising the RHEL 3.0 OS..it shows only the WindowsXP and RHEL AS4.0 in the list..

Take a look at my menu.lst (in ubuntu)

You did a small error during instalation:
You "told" RHEL AS4 to write the boot loader in MBR,  and the it overwrited the previous grub (or lilo??) instalation,  so now you should edit /etc/grub.conf and create an entry to add the option to boot from RHEL 3.0

In my case i have 3 hdd(1 ide,2 sata)  the parameter (hd0,0) means first drive, first partition, and so on
