I have solved this problem myself ,it was not a problem actually , jus not understanding SDA drives and all . So mentioning here to what I did to make it simple-

Then changes the
Boot Priorities to

Where to install like shown below -

Something Else , it was showing all my partitions along with
Free Space where I wanted to install it without afecting others and Entered the values for making
SWAP Area as 4gigs as I am having 4gigs of ram ,and rest all for root directory
(/) where everything is about to be installed.
6.After everything completes , I got what I want as shown below-
7.Remember in my question I was asking to do so with 17 gigs of partition , and in the picture its 47gigs , because i have changes the partition size for that, Its better now.
