how to change Home into HOME?

this will depend on the used theme;

please post more information.

I used twenty eleven.. i want to change my main menu Home into HOME.. ??

start by creating a child theme of Twenty Eleven: https://codex.www.ads-software.com/Child_Themes

then add this to functions.php in the child theme:

function twentyeleven_child_page_menu_args( $args ) {
	$args['show_home'] = 'HOME';
	return $args;
}
add_filter( 'wp_page_menu_args', 'twentyeleven_child_page_menu_args', 20 );

or activate and use the custom menu under:

dashboard – apperance – menus
