I trusted a tech in a store have access to my computer and HE COMPLETELY WIPED OUT MY HARD DRIVE WITH A NEW INSTALLATION!!!! 
The new installation is GPT and completely wiped out the two partitions I had previously set up on the internal hard drive. The technician claimed that he thought that the hard drive on this 2013 computer was empty...! And refused to take any responsibility for my TERRIBLE LOSS. I have VERY IMPORTANT DOCUMENTS on this hard drive and my life will be considerably more difficult if I cannot recuperate those documents. I tried to recuperate the lost files using RECUVA and Photorec but neither was up to the task and the files have not shown up.I decided to try to recover the old partitions and performed a Deep Scan using Test Disk. But the result, (which took about 18 hours) does not show any NTSF partitions. I am seeing several (18) partitions listed and NONE are labelled in such a way that I can understand or intuit what they are about. They are all MS Data as opposed as what I was hoping for, which is of course, NTSF. I am now using the same computer to write this and have avoided installing any software. So I don't have a way to send a screen snap shot. If there's anybody out there who knows their stuff and can help, HELP!
