OK. So, I redid some steps and clicked the minus signs and clicked apply. It did it's thing and then said it failed. This is what my D/U shows now: https://imgur.com/0PgM5Ue

I can click erase now though but will wait upon further instructions since something failed. I don't want to make this worse than it is.

Update: I redid some of the steps and then it took, so now I am ready to erase my HD. My question is this: Since my HD says it has 121.33 gb of space, does it mean that Sierra is still on it? If so, why do I erase since the other two partitions are not showing anymore? Or is it already erased, so then why erase? Silly questions if you know the answer, but I don't. I am ready to erase and then port back my Sierra 2015 from my ext drive, just wondering about this first.

By-the-way I'm glad you had no trouble getting the download. I had not tried that relatively new iCloud feature before and wasn't completely sure how it works. 👍
