I would suggest you select the option to 'Try without Installing' and when you get to a Desktop, open a terminal from the menu or by holding down the Ctrl+Alt+t keys simultaneously. Then type: sudo fdisk -l(Lower case Letter L in the command). This will output your drive/partition information which you can post here.
I would also recommend that when you select the type of installation you select "Something Else" rather than the "Alongside" as you wil get a lot more control over the installation and see what is happening. If it isn't detecting the ntfs partitions and you just install, you will probably overwrite your windows.
The output above should show the number of partitions. Is this an OEM install?
its one hard drive with three partitions
am not getting the option to install 'alongside windows'
when selected the option to install 'SomethingElse'
the NTFS partitions inside windows is not detected
