I was using windows in my desktop. Today I installed debian in my desktop where 16 GB free space was left for it. Unfortunately I got an error message that linux can not be installed in this partition. So I decided to remove windows 7 and install linux completely. So I deleted the partition of windows 7 and linux was installed completely. After installation it was not detecting my previous another two partitions where all my data were kept. It is detecting only the file system where it is installed. Remaining part is like does not exists. My all data and many important documents are missing. Then I tried to get the data back by installing windows again. but another big problem is that windows is not detecting HDD. Please give a solution. you can mail me anjan.k.suri@gmail.com.
