data recovery - After getting a deleted partition with Testdisk software, can I recover it on the unallocated space of the deleted partition without any problem?

I have Ubuntu and Windows 7 on my PC. My linux partition was accedentaly deleted. So, I'm trying to recover deleted partition with Testdisk, and I'm using Ubuntu Live CD since my Linux partition is deleted. I have found my files with the software, but where should I recover them. Can I recover them on the deleted partition(the unallocated space which was linux previously) without any problem of overwriting and permanent data loss?
