I am trying to do a clean install on my Macbook Pro 13" from 2011. Here is what I did so far:

1) Booted up on my USB Stick with Mountain Lion Installer mounted on it

2) Opened up Disc Utility and formatted the Hard Drive. On this step I selected that I wanted to encrypt it as I always did and put my usual password in it

3) Exited Disc Utility and started the Installation process

Problem: It froze on 18min left and I waited for about an hour. Following a post on the apple forums, I simply reseted it waiting for it to resume. However it did not come up.

When I enter Recovery Mode, the Hard Drive is not there anymore. And I think because of that I get a error message when trying to execute the installation again, telling me to try again because it failed (doesn't even start).

I am hopeless now. Tried opening the terminal and listing the volumes available by

diskutil coreStorage list

But it says there is no volumes to show. Already tried reseting the NVRAM as well.

Is there a way to restore the hard drive and restart the installation?

    diskutil coreStorage list won't return anything if you don't use a Fusion Drive. diskutil list will. Dec 6, 2013 at 7:24
  • ok thanks for the heads up. I used coreStorage because that is what I have used before and worked.

I gave it some time and tried reseting the NVRAM again (cmd+P+R on start-up).

This time it did work, or I did something wrong on the first time, I guess. The Recovery Mode opened up and there it was the "Macintosh HD" listed again.
