I am under the impression that should you wish to reinstall an OS onto your 2012 MacBook Pro, it would have to be the OS that came with the machine originally – maybe Lion (10.7) or Mountain Lion (10.8), though it's possible that depending on when the laptop was purchased, it may be Mavericks or Yosemite?

As I understand it, your machine will not accept any OSX after that and only when you reinstall the original and specific OS that came with the machine can you then begin to subsequently reinstall a later-period OS.

Disregarding for the moment whatever the state of your current installation attempt is, and I'm afraid I am unable to comment usefully on that, it may well also later become an issue ensuring that your machine will even accept the 'original' OS that came with the laptop. It may be that you would have to 'circumvent' the more usual reinstallation process (ie, that which would have been appropriate at the time of the OS), partly by preventing the laptop from ascertaining the current date at which you are attempting a reinstall, which of course is many years later. (It would be able to ascertain the current date if/when connected to the internet).

The reason for that potential complication is that the old OS (Lion, Mountain Lion or whatever) will no longer have a valid signature (this may not be the correct terminology) or other functioning reference that would enable the MacBook reinstall to complete. Manually amending the date and time on your laptop to a period specifically relevant to the old OS you are attempting to reinstall would 'trick' the process into working as though all is as it should be. A bit of 'sleight of hand' time travel, as it were.

I'm not quite sure what exactly it is you have done to get to the situation you are currently in with your MacBook. Maybe other forum members will have additional or more useful insights than mine that will assist you further in your efforts. Good luck.
