If you use a seperate boot partition, you can load the kernel from a primary partition then boot into an extended partition. Many different Linux OSes can share one boot partition, too.

I first installed Redhat 5.
After that i installed Ubuntu 8.10.
I am unable to boot into Redhat.
In the menu Redhat is not shown as the MBR is overwritten by Ubuntu GRUB.
GRUB couldn't possibly keep all its settings in the tiny amount of space a boot sector gives, it's actually smart enough to understand some partition types, to let it reach in and grab a config file. Usually /boot/grub/grub.conf, whichever partition that ended up at in your file tree. It'll be reading the new grub.conf instead of the old one now, but if you can get your old one, you can add settings from it to your new one.

Now how to make the dual boot ??
You can't just install lots of OSes on top of each other and expect it to work, you need to plan ahead. It may still be recoverable at this point if you can find the grub.conf from your redhat partition. Post both your new and old grub.conf files here, in code tags, and we can help you make a grub.conf that can boot either.
