I am a new user here and also on Ubuntu. while installing Ubuntu, my hard disk was formatted accedentally and i lost all my data and partitions also. Now i have only ubuntu as Os and my windows installation is also deleted. I want to get my data back, but don't know where to start. I have been reading Testdisk wiki and forums here last week, but unable to understand how to proceed. Can anyone simply list down steps i need to do. e.g. do i need to recover partitions first and then files or simply files( I really don't understand from wiki
