This question already has an answer here:

I am a beginner with Ubuntu. I have tried installing Ubuntu yesterday in C drive. However it took over the complete hard disk space. I dont see my data. After doing lot of research on internet got to know that with the help of disktest tool that can be recovered. I tried booting from live usb and installing testdisk on the that. I was successful in analysing the cylinders. Got to see all the NTFS derives. But once i selected one of the drive and pressed enter it did not give me any option to recover it on external disk. Please help.
