I'm am new to this ubuntu but wanna use it. I got a HP laptop with 1tb hard disk in it with windows 7 as default os i had erased my windows and installed ubuntu 13.04 fresh. So can any one help me how to create ntfs partition so i can store my files, movies etc in it please.
Here is a good manual for creating partitions using Gparted, and includes pictures.
First, install gparted from the software center, or via command line:
$ sudo apt-get install gparted
Run gparted from your applications, you'll be asked for your root password.
You'll be presented with a list of your exsting partitions. You can re-format a desired partition by right-click and unmount, then right click, and choose a new filesystem. Once done that - click on the green tick above, that will write changes.
You should then have a valid ntfs partition to install Windows. Good luck!
