Erased HD Volume- need help.

macrumors newbie
I just received my new macbook pro and accidentally erased the volume hd (one that shows 500gb and specs etc) upon a reset. It doesn't show in Disk Utility. All that appears is Macintosh HD which the utility will only allow me to verify and repair just like the original poster. The Mac boots directly to the Utility Menu upon restart. Ive tried the recovery system, and the only disc I can get to show upon reboot is a recovery hd but it is locked.

Any help would be greatly appreciated! Thank You!
 
Hi,

did you try to boot with Cmd + r depressed ?

The OS X Utilities window should show up and let you re-install from Internet.
 
Yes, I did. The internet recovery (globe) initiated, loaded, and returned me to the utility menu.
 
When it gets to select drive to install it shows only a recovery hd which says it has been locked when i attempt to select it.
 
You may need to go into Disk Utility and recreate the partition to enable you to install OS X again
 
when i go into Disk Utility Macintosh HD shows up but it doesn't allow me to do anything to it. All the fields are greyed out.

Does it show Macintosh HD twice like in my screenshot?

No it just has Macintosh HD once

as such:

Macintosh HD


disk1
-- OS X Base System

Try this. Make sure you are in Internet recovery and not regular recovery. (It sounds like you are from the globe description) Hold command-option-r (all three at once) at boot and pick your wifi and you should see the spinning globe, then the recovery screen.

Now start Disk Utility and go to the erase tab. Select the drive band name itself at the very top of the left column above Macintosh HD. Now select Mac OS Extended (Journaled) in the dropdown to the right and apply that change.

That should erase the whole disk. Now quit Disk Utility and click reinstall OS X at the top.
 
when i enter internet recovery, the globe spends with the progress bar and timer beneath it and once its loaded the apple symbol reappears, load and sends me back to OS X Utilities.

It should get you to this screen. Is that what you see?

It looks just like the regular, disk based recovery screen, but it is running in RAM from the download and not the disk.
 
yes, thats exactly what I see.

----------

However, it didn't ask me to sign into my wifi network but it loaded and returned me to the screen above

That's fine. So what happens when you try and use Disk Util like I described?
 
when i select Macintosh HD everything pertaining to it is greyed out with the exception of the verify and repair disk options. Everything in the Partition folder is grey.

Read what I explained again. Go to the erase tab and select the disk, not Macintosh HD.
 
sorry about that. There is nothing above Macintosh HD but the Verify scope. the disk 1 and os x base system are beneath and all options to reconfigure are greyed.

Hmm... just to be sure... you are in the erase tab of Disk Util?

Let's back up a little. Why did you do this and can you explain step by step what you did?
 
I was attempting a hard reset of my mac and suspect that I deleted the volume hd. Unfortunately, I'm up against an engagement and can't continue to troubleshoot. Ironically, I went through another thread and you helped someone through an almost identical occurrence although his fix didn't work for me. So, I was happy when you jumped aboard to help. Thank you anyway. Your time has been very well much appreciated.

You are welcome. Shoot me a PM if you want to revive the thread and take another crack at it when you have time. :)
