reset query_posts

hi is there any way to get this loop reset??
i m trying to run this loop

– get_post_meta($post->ID, ‘side’, true);
then

<?php $myposts = query_posts("cat=10");
foreach($myposts as $post) : ?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>

-then get_post_meta($post->ID, ‘slideshow’, true);
-then another

<?php $myposts = query_posts("cat=10");
foreach($myposts as $post) : ?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>

but it seems not working when the get_post_meta() run after the

foreach loop

is there anyway to reset or ……
