That looks like the Quiz administration menu, not the Course administration one.
One thing to check beforehand though: go to Site administration > Badges > Badges settings and check that 'Enable course badges' is ticked.
Then (in the Boost theme*) go to the course, click on the cog, click More, go to Badges > Badge settings.
If you can’t find the link, you can go directly to it at yourmoodle/badges/index.php?type=2&id=2 where id=2 is your course id (you'll find that in the web address of your course, it will look like yourmoodle/course/view.php?id=2
*the Administration menu will be in a different place in other themes, and most likely will not use the cog!
