Help, restored Macintosh HD to OS X Base System

Help! I accidentally restored Macintosh HD to OS X Base System. Didn't know that would cause issues... I can only open my laptop through the Command+R thing with macOS Installer.

I was just trying to delete everything and start my Macbook fresh. I tried to re-install OS X Sierra, and it keeps failing. When I go to disk utility under internal, there's no Macintosh HD there's only OS X Base System.

Tried to ask Apple Support for help and they first told me to try first aid and that failed.

They told me to go to a service center, but I wanted to see if there are any solutions I could try.

Thanks!

It's a 2015 Macbook Pro.

Hi there, does anyone know of a way to do this without Internet System Recovery? I have had the exact same problem but on an old 2009 iMac so it only has the standard recovery process (CMD + R). I need to restore my old "Macintosh HD" to /dev/disk0 instead of only seeing the OS X Base System. Trawling through online forums, people have had this sort of problem when there's a HDD failure or a cable problem, but mine is a direct result of restoring the OS X Base System over the primary internal drive.
