recently i have installed Windows 7 on my laptop. i was using ubuntu. i had some important documents in ubuntu. i forgot to take back up of that documents and i formatted my laptop and recreated new partitions.
now i am trying to recover the deleted documents from my hard drive but don't know how can i get my files recovered?
is there any free software that help me to recover my deleted data?
i did try Ease us Data recovery but it doesn't show anything.
any help would be greatly appreciated.
As already pointed out in the comments on the question itself, having the drive already re-partitioned and installed several GiBs have lessened your chances drastically – but there might still be a chance, at least for parts of the data. First, let me repeat Mawg's advice to not use the drive until your recovery is done, specifically don't boot from it – or your chances will get even smaller.
Try recovering data while booted from a different disk – a Live-CD is best fitted for that. I've had good experiences with TestDisk in the past: it is available cross-platform, and knows a lot of file systems and data types. They even have such a TestDisk LiveCD available which you could use for that, so no installation required.
For alternatives, you might wish to take a look at the data-recovery tag-wiki of our sister-site Android.SE, which offers useful links. Good luck!
