Macbook won't boot!

Hi all,

Looking for a little help and guidance, as I am stuck.

My MacBook Pro from 2012 get stuck on the boot when I turn it on, the progress bar does appear below the apple logo, but moves so slow, and eventually just switches off. I have booted into safe mode, and got to the disc utility, where I was going to try re-installing the operating system. But in disc utility it doesn't even show my hard drive.

Any ideas on what I can do, from my view it looks as if the hard drive may be broken, but I don't have any clue.

I'm running macOS high sierra btw

Many thanks in advance,

Marc

MacBook Pro, macOS Sierra (10.12.4)

No disk in Disk Utility usually means the disk has failed. Replace the disk or try using an external disk as the boot disk by using:

Boot Using OPTION key

Restart the computer.
Immediately at the chime press and hold down the "OPTION" key.
Release the key when the Boot Manager screen appears.
Select the disk icon from which you want to boot.
Click on the arrow button under the drive icon.

You can also boot from the Recovery HD if that is still possible:

Boot from the Recovery HD

Restart the computer.
Immediately at the chime press and hold down the "COMMAND" and "R" keys together.
Release the keys when the Apple logo and progress bar appear.
Upon completion, the Utility Menu should appear.
