Oct 20, 2013 6:27 AM in response to Jennseay0393by Tony T1,You have to select "Reinstall OS X" (unless you have a Time Machine Backup)
Any data previously on your HD will be unrecoverable after this.
(If you need to recover data on the drive you accidentially erased, Quit and use Data Rescue )

Oct 21, 2013 3:49 AM in response to Jennseay0393by R C-R,Startup again in Recovery mode (command + R) or if that doesn't work try forcing Internet Recovery Mode with command + option + R. Once the startup process is complete & you see the OS X Utilities screen, choose Disk Utility.
Once that is running, select your internal hard drive from the list on the left (not the volume name indented below it). If you have chosen the drive (which typically has a name suggesting its capacity) you will see a "Partition" tab in the Disk Utility window. Click it. From the popup choices for "Partition Layout" choose 1 partition. Make sure the "Format" choice shown is "Mac OS X Extended (Journaled)." Click the Apply button & confirm that you want to repartition the drive.
Wait for the process to complete. If it does without displaying any errors, quit Disk Utility & now try selecting Install (or Reinstall) OS X from the OS X Utilities menu.
If you get any error while doing the above, report at what step it occurs & what the error is.

Boot while holding the option key.
You should see Recovery HD.
Select it and try Reinstall OS X again

Thank you so much!
By the way, it says 62 hours until done. Does it really take that long?

How long it takes depends in large part on how fast your Internet connection is, since it is downloading several GB of data. However, the estimated time to completion is not very accurate. Typically, it starts off greatly overestimating the time, then counts down faster than in real time for a while, & then settles into a more accurate count until near the end when (annoyingly) the last few minutes shown can take several times that long.

Oct 22, 2013 2:16 PM in response to Tony T1by Jennseay0393,Ok so I'm in setup process now of installing Mac OS X. On the step I am on currently it is asking me if I would like to transfer information from another Mac, time machine, or another startup disk. Just checking, but I answer no correct? Since all my data was lost I don't need to get info from startup disk, cause there's nothing on startup disk?

As you do not have a Time Machine Backup, or a Backup on another drive or Mac, answer No.

Aug 29, 2016 10:47 AM in response to Godlyfrankyby Eric Root,You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.
Can you click continue? If you can't do anything, try a restart.

Sep 7, 2016 5:34 AM in response to Jennseay0393by Vishal2014,No doubt, you did a huge mistake by restoring your Mac without a backup copy. You may get some relief by recovering 1 GB of deleted files for free but to recover more data you might have to purchase a Pro version of Mac data recovery software. Do not forget to clone or backup your files with Time Machine next time.
