My bootcamp does not show select task option. what should I do

Hey, i am using macbook pro mid 2015 (MJLT2). i want to install windows server 2012 r2 with bootcamp on my macbook pro.

The Problem is that:

When i start, bootcamp does not show select task options. I have downloaded bootcamp support software directly from internet because when bootcamp automatically downloading support software, its very very slow and sometime it stuck. I have tried many times. What should i do ?

Can i install windows without bootcamp ?

Please Help Me!
