Hi,
Here is a link which shows how to replace a screen on a HP Envy M6 1225dx (I realize that it is not your model but it should be of some help).
At 3:10 minutes into the video the bezel has been removed. If you start again at 7:35 minutes into the video you will see how to replace the bezel.
Here is the link.
