a boot may or may not work. if the pic shows the tire inflated as you like it, it looks pretty good as is. if the pic shows the tire deflated. put a boot in it or patch it from the inside (as recommended) and take a look. the bulge, if any, and your judgement will determine whether or not it is salvageable. i've ridden on a couple of damaged tires that bulged a mm or two for quite a while.
