Double Loop Problem

I want to make two loops for my index page. the first one should include titles and contents and the other one should include only titles. i did it and they are working but there is a problem. when i click a title then in the title loop there will be shown only the title i clicked. but i want to show there all titles even if i clicked a title. how can i fix it?

the titles loop code:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post();  ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
 <?php endwhile; else: ?>
<?php _e('There is no post yet.'); ?>
<?php endif; ?>
