Do you have access to a second mac which has a Thunderbolt connection and a Thunderbolt cable?
I think you'll need to scratch the drive and re-install the OS. By leveraging the second Mac we can setup your system like a HD to it using Target Disk Mode.
The other option here is to setup a USB thumb drive as a bootable drive using the other Mac system and installing on it the OS installer. Here's the steps for that:
- Get a USB thumb drive (16GB or larger)
- Download the OS installer from the App Store, make a backup copy
- Then create the GUID partition map on the thumb drive and format the partition with Mac OS Extended (Journaled) with Disk Utility.
- Run the OS installer and install the OS onto the thumb drive.
- Once done, copy to it the copy of the OS installer.
- Restart your system holding down the Option key so you gain access to the boot manager select the thumb drive.
- At this point you should be able to reformat the drive using Disk Utility on the thumb drive and using the OS installer on the thumb drive install a fresh copy of the OS.
Do make sure you are connected to the internet as there are some updates your system will need.

When you see a circle with a slash symbol instead of the Apple logo, it means your Mac couldn't find a valid System Folder to start up from.
Your machine shipped with 10.9 and will not boot from a lessor system.

No, it's a 2012, and automatically reinstalls OS 10.8 from the internet.
After the install is complete it won't boot.
Olly sorry, the machine you selected the icon is a late 2013.
everything indicates that the Hdd is dead, damaged, (go out and purchase a new drive). but wait you can see it in Disk Utilities run restore etc but it will not load the iOS 1. Unmount the Hdd then format the drive then remount the drive. re boot from disk util run restore install the latest iOs via your netwk. find a USB to access the system. as with last reply.

This is a Mac not an iPhone or iPad. The OS is MacOS or OS-X not iOS.
iOS, doesn't that mean "internal operating system"? lol
