What I'm trying to achieve is:
I've been searching for the whole day without result. Could anybody help?
Here is my code so far:
add_action('after_switch_theme', 'my_after_switch_theme');
add_action('after_setup_theme', 'my_after_setup_theme');
function my_after_setup_theme()
{
register_nav_menus(array(

$menu_check = get_option('menu_check');
if (!$menu_check)

$primary_menu_items = array(
'Home' => '/',
'Menu item 2' => '/',
'Menu item 3' => '/',
);
generate_nav_menu('Primary Menu', $primary_menu_items, 'primary');
}
}
function generate_nav_menu_item($term_id, $title, $url)
{
wp_update_nav_menu_item($term_id, 0, array(

Looking at the code for wp_update_nav_menu_item() the third parameter is an array of data about the menu item you are trying to update/create. One of the accepted items in that array is menu-item-parent-id. If you pass that key with the value of the ID of the parent menu item as part of the menu item data array then your problem should be solved.
EDIT: I haven't tested this, but in theory, and assuming everything you had before was correct, this will work for you
