function getMainMenu(){
	$locations = get_nav_menu_locations();
	$menuItems = wp_get_nav_menu_items( $locations[ 'primary' ] );
	if(empty($menuItems))
		return false;
	else{
		/*My own custom menu*/
		return true;
	}
}

u have to create your own getMainMenu function in functions.php
ur getMainMenu function should return true or false

the code i post above should be pasted in where every u need to load the navigation menu.

hope this helps

It works! Thanks.
But i have a better solution for those who have their own function to get the menu.
if(!getMainMenu()){
$backup=$wp_query;
$wp_query = NULL;
$wp_query = new WP_Query(array(‘post_type’ => ‘post’));
getMainMenu();
$wp_query=$backup;}

notes:My getMainMenu function returns false when it fails to retrieve menu.

With this way, i don’t need to adapt the solution in every theme files that requires it.
Hope it helps.
