it gives me about 4 choices of what to do.
I'm guessing this is something like "Continue", "Use a Device", "Troubleshoot" or "Use another operating system"?
And you chose the second option, I assume?
The procedure says to chose the boot drive but it lists several other choices, recovery device being one.
Let's say you have an Ace of Spades, a Queen of Clubs, and a Jack of Hearts. Now, a procedure says to "choose the ace of spades".
I assume those instructions are reasonably clear. How is it relevant? well, what you are saying is sort of like saying in that situation that "the procedure says to choose the ace of spades, but there are several other choices, the Jack of Hearts being one". The instructions, after all, specifically tell you to choose the boot drive (the device you want to install to) because there are likely to be multiple options.
(I assume when you say that it lists other choices you mean the boot drive/HDD you installed is listed appropriately)
