Hello Syed Rehman, You can't do this because of Jquery Modal Popup is working on same Page and You can't Load the other Page inside Jquery Modal Popup I would like to suggest to use windows Size for Other Page that Look Like Popup Just check the Example.
// set this on OtherPage inside script.
<script type="text/javascript">
var size = [400, 300];
$(window).resize(function () {
window.resizeTo(size\[0\], size\[1\]);
});
</script>
//Now Set the Link on first page.
Open Other Page
