cv boot – help

Before some of you start stirring jokes around , I’m not a mechanic and never done this before- nothing like it. oil change in my work van is all I can do [ and brakes…] I’ve watched some videos but none of them answered my question.
I need some help with replacing my cv boot. 09 sportsman 850 , rear inner. [left].
Q: are both sides built same way [inner& outer]? I have a trouble with taking one part out.there is some "wire" in between the threads… and to take boot off i need to take this one out as well… how to ?
