Q: file recovery after partition deletion

Hi all, again, i've seen all this come up in the past, but i had to install some repair drivers as my mac functions were not working properly after the windows 10 update. it also meant i was unable to use my macbook's trackpad too! I accidentally selected the option on bootcamp assistant to delete an existing partition and have now literally lost all my college work and everything. Is there anything at all i can do to recover files?

MacBook Pro, null

Shutdown you Mac, power it back up and use the Alt/Option key. Select the USB from the Apple Bootmanager list.

Can you post a screenshot? It may just be the shell prompt.

Run diskutil list. From the output choose your internal disk, let us say /dev/diskN.

Post the output of sudo gdisk /dev/diskN (use N from the list above as appropriate).

This is strange. On a 320Gb disk, you have 16Gb OS X and 95Gb Windows. Where is the rest of the disk space?

Can you post the output of sudo gpt -vv -r show /dev/disk0 ? If you incorrectly entered the start/end of GPT 2 in the steps, it can cause this problem.
