Yes, to your question. Choose option 1.
I would disconnect the second drive first though, if your G73 is anything like my G74 its absolutely no problem to do this. Just CAREFULLY pull the tab connecting it from the machine. I would also back up everything you don't want to lose if you haven't already. Back up back up back up is a personal mantra to me as I've lost way too much stuff over the years. If you have an external you can use I highly recommend using that. While this a very simple straightforward procedure ANYTIME you do anything with drives or volumes (partitions) you run a risk.
