Hard disk "not mounted" High Sierra installation

I'm trying to install macOS High Sierra and when open the Utility Disks' window ( when restart and hold "Alt") my hard disk internal results "not mounted" , I had "first aid" and it works, not issue. I have a Macbook pro late 2011.

Any advices ? Thank you

MacBook Pro, macOS Sierra (10.12.6)

Hi,

Resetting NVRAM could solve the problem.
