Open /etc/grub.conf and change the default value for linux.

Sayan, he installed Win Xp after RHEL, so windows has over written the Grub or whatever boot manager installed.

OP, you would need to boot from RHEL cd into rescue mode and then reinstall grub.
At the prompt

grub-install /dev/sdX. X is the device name in your system. Change it appropriately. It should most probably be sda.

And I would personally not change a file that is a symbolic link and would rather tend to edit the file itself. So I would edit /boot/grub/grub.conf instead.

Oh, did not notice that.

The OP didn't say that the linux was not accessible, so probably could just change the boot.ini to what is required.

well, if the OP can't boot into linux, he should install the grub first, changing boot.ini won't be a good idea, i guess.

Agreed. Grub handles dual booting much better than windows. So we should just let Grub do that.

I'm not sure if the OP has an entry for linux in boot.ini, it should not be there actually.

Not necessarily agreeing or disagreeing with the various Windows/Grub boot system comments. I'm just saying it can be done either way.

Yes it surely can be done but I am giving my personal comments. I would always like to keep Grub boot manager rather than allowing windows boot manager to boot linux.
