Since you installed another OS on top of linux, the linux grub bootloader got uninstalled.

All you need to do is to install the bootloader again...which is very simple in your case

Were u using grub or lilo as the bootloader?
grub is the choice by default during the setup.

If you were using grub , then, In your case, the grub configuration file grub.conf still exists on the linux partition.Just do this:

1.Boot from the RedHat Linux Cd 1

2.Choose rescue mode

3.Do a chroot /mnt/sysimage

4.Give this command:

/sbin/grub-install /dev/hda

This will reinstall grub on the MBR

Thats it...

reboot, and you will have grub again, and you will be able to boot all the os'es from grub.

If you were using lilo, let me know and ill give you further instructions.

Np and anytime mate.

I am glad atleast some one was sensible enough to search the forum archives for a solution to his problem and follow the guides that were already there on the forum instead of staring a thread about something that was already answered..So thanx for being sensible.I hope others follow your example.
