MacBook starts to a grey screen with a circle with a line through it.
I was trying to restart my Mac by the following instructions on another forum and somehow my Mac crashed. Now when it starts up it opens to a gray screen with a circle with a dash through it. Can someone walk me through how to fix it? also not very tech savvy 🤦🏼♀️
Below is my disk utility
MacBook Pro 13″, macOS 10.13
