I like to set a default OS. I have two OS in the same machine. Can anybody help me in this issue?

Not with that little information. You would need to at least post which bootloader you are using because the method will vary.

If u hv 2 os what is the other one or what's ur default boot loader.
if u hv centos then modify in
/boot/grub/grub.conf

Find which one is default and u can modify from there.

If u hv window then edit boot.ini

Per the LQ rules, please don't write posts like this; instead write words out in full, as they're easier to understand that way.

In your terminal type in vim /boot/grub/menu.lst not /boot/grub/grub.conf Now that depends on the editor your are using, could be vim, emacs, nano but what ever it is <editor> /boot/grub/menu.lst

You need to be root to modify the file so just log in to a terminal as root and open whatever the default text editor is or use vim as suggested to open /boot/grub/grub.conf. I believe there is a menu.lst file which is a link to grub.conf.
