Accidentally formatted the partition which contains my back up

Question

I dual boot Ubuntu and Windows 10 but I accidentally formatted the Windows partition which contains all my backup. How can I recover data on that partition?

Answer 1

Use TestDisk

it's command line based tool which can recover almost all of your data, even in NTFS partition. I wouldn't use it to recover an OS but media files and documents in the partition should come back. you can even choose what files you want and it's a really powerful tool if you first read the complete instructions

to install testdisk and start using it, type these commands into in terminal

sudo apt-get install testdisk
testdisk

Here is the Official step by step guide to use test disk
