Every boot I have to click my HD

[JustinBW]

Every time I restart or boot I get a grey screen that shows my HD's partitions.

I am not sure why this is happening, I thought the user had to hold down the option key or something to do this.

The only partitions on my hard drive right now is the OS (Yosemite) install and the automatically created recovery partition.

Any ideas how to prevent this from happening?

So the real issue was that the startup manager was showing every boot - I found this thread - https://forums.macrumors.com/threads/1721632/ after a google search

And resetting the NVRAM did fix the issue: https://support.apple.com/en-us/HT204063

I was going to delete the thread, but I think keeping it open (with the screenshot) might be useful to other users.
