Solution
You have to reformat the HDD as part of the process (or select a new partition). You will not save any of your previous settings or files as part of the process. Just keep that in mind.

I tried that but when during installation the setup asks for a disk partitioned although theres a plenty of space available but when I click on any disk a message appears saying that windows was unable to find disk partition.
