OK. Here's an example of where someone says something and thinks I can read between the lines. I went back and looked at Disk Utility and saw the 3 partitions. I had clicked on the partitions like I was told to but no one said to actually click on the minus signs! I was told to click on the partitions one at a time and then click "apply". So, just now I clicked on the minus signs and now I can click apply! I am going to see what else I can do now.
That's it. (I think it used to be called Repair Disk, anyhow.)
