This question already has an answer here:

So, I had Windows 7 on my hard drive. I decided to dual boot with Ubuntu 12.04. I was in a hurry and hit the wrong button, so it wiped out (full format) my Win7 install. It was a NTFS drive, but was formatted to ext4. I didn't realize it until about an hour of usage. There was lots of important data on there. Is there any hope of recovery? EDIT: As soon as I realized that the data was lost, I shut the computer down.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

First, stop using the drive and switch to a linux live CD. Now. Then search SuperUser for data recovery questions. – Darth Android Jul 11 '13 at 16:31
testdisk. immediately. be sure to recover to a differant physical disk of the same or greater capacity. – Frank Thomas Jul 11 '13 at 16:31

Your only hope of recovery of the data is to use those fine backups you have made on your windows 7 system. Hopefully, they are safe and fairly current. Otherwise, the answer is pretty much NO your content is Lost.

If you wish to spend a lot of money to a data recovery company, perhaps some or most of the content can be restored. But you have to weigh the cost against the value of the information.

Data Recovery companies can't recover overwritten data from modern hard drives. What wasn't overwritten might be salvageable, but it's probably not much at this point. – Chris S Jul 11 '13 at 17:08

Listen to @Frank Thomas and try testdisk - which you can get here - but pull the drive out and put it in a USB enclosure or non-boot SATA port.

You've likely lost some data, but you can try to recover what you can using the above.

I think I have a USB enclosure lying around somewhere... I will try that. – weatherkid Jul 11 '13 at 16:42
I tried testdisk, but it couldn't recover anything. – weatherkid Aug 6 '13 at 19:40
