"Are you sure it's "D" you are using when restarting?"
Yes, I am 100% sure. But I understand why you are asking: I am surprised at it myself! You see, my original plan was to see if I can somehow repair the system using "D", then try "Cmd+R". But, to my surprise, D invoked the options I mention so I sticked with that. I have absolutely no idea why it works like that for me, seems most irregular. Maybe only "Cmd+R" will work for you?
As for you only having an option to reinstall Sierra… can you remind me what version you are upgrading from? If it's Sierra, then it's understandable. I was upgrading from High Sierra PB1 to PB2 and from PB2 to PB3 and, AFAIK, this function reinstates the most recent version of the current system.
Ugh. I hope I am making myself clear
