It looks like you have FileVault turned on there.

Run this command and it should give you the name of the FileVault volume.

Code:
diskutil cs list

Then once you have the name of the volume, run this command inserting that name in the quotes. In my example the volume is Macintosh HD.

Code:
diskutil cs delete "Macintosh HD"

That will wipe and kill the encrypted volume. Then go back to Disk Util and erase the drive.
 
My HD recovery was lock but not sure what command I change in the terminal but disk utility is showing fusion. Please help!

My HD recovery was lock but not sure what command I change in the terminal but disk utility is showing fusion. Please help!

Make sure you are in command-option-r Internet recovery, then in Terminal run this command to delete the fusion drive.

Code:
diskutil cs delete fusion

Then select show all devices in Disk Util and pick the disk itself at the very top and erase the drive to Mac OS Extended. Then reinstall the OS.

Hmmm... this is confusing because your earlier screenshot shows a core storage volume.

Can you configure Disk Utility like I described above and erase the drive?
 
Did I do it correct?

There we go... that should have removed the core storage volume. Now go to Disk Utility and select the drive at the very top and erase it, then reinstall.

I'm not quite sure how you got in this mess, but here is how to fix it. (I am assuming here there is not some underlying hardware issue that got all this started).

Hold command-option-r at boot and select your wifi when asked. Then you will see a spinning globe while the recovery utility downloads and installs. Once that is done you will see the recovery screen. From there launch Terminal from the Utilities menu and enter the line below exactly like I have it, including the quotes. That will blow off the Fusion drive.

Code:
diskutil cs delete "Fusion Drive"

Now quit Terminal and launch Disk Utility. You should see a screen like this offering to fix the Fusion drive. Go ahead and click Fix to rebuild the Fusion drive.

Now quit Disk Utility and click reinstall OS X at the top and wait for it to finish and restart. This will put you on the OS X version that came from the factory. You can update to El Capitan after if you like.

What you are seeing locked there in your second screenshot is the Recovery HD partition, and that is as it should be and not the problem. The problem is you borked the Fusion drive somehow and this will fix it.

Why did you do this to start with? Were you having some problem that made you try a OS reinstall?

Do you happen to have a USB key OS installer?
 
whats up man! Yes I was having issues with boot once in a while and was trying to see if it was a software or hardware issue. I probably reinstalled OS about 3 times with no other issues. Originally El Capitan but with high Sierra I’m having issues... no I do not have one of those. Is it the only way?

I'm wondering if you have a drive starting to fail. That would explain the boot issues and now the disappearing drive.

You are sort of in a fix here, because your 2009 does not have Internet recovery to reinstall the OS, so you would need to somehow get a USB OS recovery key made. Do you have access to another Mac where you could make the recovery key?

A total bind my friend. That’s exactly what I’m doing right now! I hope it works
[doublepost=1554162244][/doublepost]Except for I’m running on Mojave on my 2012 Mac air and when I download high Sierra it says it’s not compatible... it’s literally impossible.. if you had time to call me I could Venmo you a few bucks or something 7025179515
 
Hi Weaselboy,

I really need your help.
I have press command-option-R to boot to internet recovery mode, but spinning globe didn't occur but still boot to recovery mode.

Can't erase disk and reinstall OS X.
Please help me to solve this problem.
Thanks.

Macbook Pro 2011.

The problem is you are trying to format the drive while you are booted to it in recovery, and that won't work. You need to either option key boot to a USB installer key or command-opyion-r boot to Internet recovery.

Your 2011 MBP is listed in that linked support document as having Internet recovery. Are you sure you have a 2011 and not an older model?

When you boot holding command-option-r do you see an option to chose a wifi connection? You should see that before the spinning globe.
 
That MBP does not have Internet recovery, so you will need to somehow access another Mac to make a bootable installer using the instructions at that link you found.
 
Hi Weaselboy,

I couldn't install OS X from bootable installer.
Already follow the instructions from those link.

Once you were option key booted to the USB key, did you use Disk Utility to erase the whole drive?

You need to select the drive itself at the very top then erase to Mac OS Extended (Journaled).
