You can use TestDisk as a rescue for Windows or Linux partitions, but you’ll need an Ubuntu live USB drive so you can boot into a separate environment on your PC, and then retrieve the lost files.

Perform low-level disk repair and file recovery--from a command prompt or DOS box--with free utility duo TestDisk and PhotoRec.

Recuva (Windows) Recuva is a user-friendly Windows-based tool. When you run Recuva, you can resurrect missing files using either the file-recovery wizard or the application's manual mode.
