I have googled this topic a lot, but for some reason the way they do it doesn't work for me. I have a 256GB SSD, and I'm trying to install Linux on it, and I partitioned it and I want to go back to having a combined drive because there is a step that requires the drive to be non-partitioned (if that's a word). Everywhere I go, it says that I just delete my partition and then go to my main drive and hit extend volume. The thing is, the "extend volume" button does not work for me. It will not let me select it. I attached some pictures with this post to show you what I mean. Can any of you guys help me? all help will be much appreciated
