I have a system which has window originally. while i was installing ubuntu , unexpectedly i formatted the whole 500GB system(which constitutes 2 partitions). In spite of overwriting it only over C drive which leads to loss of all the data i have in my system. Is there any ways to recover my data (which was present initially) from ubuntu ?

I have tried to recover data using hiren's boot and helix 3 softwares but didn't get proper method/documentation to recover data.

Try these; Parition Find and Mount, Test Disk and Rstudio. Put them in Hiren's CD.
Best of luck!
