Q: file recovery after partition deletion

Did you delete your Windows partition using BCA? If yes, you may be able to use Testdisk to scan and see if it is recoverable.

You can download it from http://www.cgsecurity.org/wiki/TestDisk_Download . It is a good tool. You can see the initial startup screen at http://imgur.com/a/PjmnK .

I am on a 13 in MBP late 2011. I modified BC info.plist for usb intall process of windows 8.1 because of broken optical drive. In the process I deleted my OS X drive and was left with only windows partition. My initial OS X drive contains everything I have done in the last three years of Mechanical Engineering which I need for developing my Cap stone to get this degree. Safe to call me an idiot for not creating a backup before reconfiguring my computer. Help me dude..

Can you start a new discussion? If Windows is bootable, please download GPT Fdisk from http://sourceforge.net/projects/gptfdisk/ on the Windows side. Do not do any writes to the OSX partition or change partitions in any way.

Can you post a screen shot similar to the following?

1. Do not write to the partition tables. It will negate any recovery attempts.

2. Do not use left/right arrow/cursor keys anywhere in Testdisk.

3. Select any partition and run a Deeper Search. It is unlikely that a Quick Search will show any reasonable recoverable partitions.

4. I would also suggest OS X: Installing OS X on an external volume - Apple Support and booting from it to minimize any writes to the disk that we are trying to recover.
