I have no startup disk and I cannot get the online recovery to work

I have been working on this for days... I have tried multiple solutions and none has fixed it yet. I was downloading sierra and it froze. I went online and tried to fix it. In doing so I somehow replaced my Macintosh HD with something (I believe the image). I went online for assistance and tried to delete, partition, you name it.

In Disk Utility: the internal is SATA Internal Physical Volume . Mac OS Extended and directly under is the untitled partition - both of these show much of nothing on them. Disk image has OS X Base System . Disk Image Volume . Mac OS Extended - this has 1.28GB used, meaning to me that this is where my stuff is??

When I bring up my startup disk option, there is nothing there - literally no option.

When i try to recovery using online via Reinstall macOS, I get the circle with a slash through it after a while.

I went into the terminal and entered diskutil list, I can see 5 different disks and the one with an asterisk says GUILD_partition_scheme. The macintosh HD and apple boot recovery are among them as well.

I seriously do not know what else to do.

MacBook Pro, iOS 10.3.3, im really not sure what os

Let's start with what exactly is the Mac model you have. You can give the following a try but it will only work if you have a functioning Recovery HD on the HDD and a working Internet connection.


Install El Capitan or Later from Scratch


Restart the computer. Immediately after the chime hold down the CommandandRkeys until the Apple logo appears. When the Utility Menu appears:

  1. Select Disk Utility from the Utility Menu and click on Continue button.
  2. When Disk Utility loads select the volume (indented entry, usually Macintosh HD) from the Device list.
  3. Click on the Erase icon in Disk Utility's main window. A panel will drop down.
  4. Set the Format type to Mac OS Extended (Journaled.)
  5. Click on the Apply button, then wait for the Done button to activate and click on it.
  6. Quit Disk Utility and return to the Utility Menu.
  7. Select Install OS X and click on the Continue button.
