I have installed ubuntu 13.10 in a windows xp desktop

after installing, in windows i tried to allocate free space(left after installing ubuntu in the hard disk). while doing so it has made some other partitions as unusable space.

my problem is "how to restore lost data from that unusable space?"

I have read many similar questions and the corresponding answers from people in this forum, but till now I haven't found a solution.

Could someone help me on this subject?

Thanks in advance!
