Trying to create a template without navigation and footer

If you take a look into the codex page for get_header() function, you will notice that WordPress automatically adds a header- prefix to your call. For example, using this:

get_header('sample');

Will search for the header-sample.php file. So, in your case, you should name your header file header-headerremoved.php and then call it the following way:

get_header('headerremoved');
