Okay, so This is the case. I had 3 partitions namely C,D and E on my 320GB HDD. I had windows 7 installed in "C" Partition, Now, I installed UBUNTU 12.10 Desktop -i386 from a Bootable USB. I selected "Replace UBUNTU with windows 7 (Probably the Second option while installation)". Now, I have a problem here. I see 2 partitions, namely "320GB Hard Disk" and "File System". When I click to open "320GB HDD" option. I get an error saying "Unable To Mount Location", "Can't Mount File"
I suppose that I have lost all the DATA I had on my HDD, and Now, How am I supposed to retrieve it or use this HDD and make Partitions?.. Please Help Me.
