Is about this title. I need to change my partition to NTFS and i can't because my HDD is occupied with Ubuntu.

1Question does not make sense. You can't unmount the partition the system is on, nor can you "change" it to ntfs. What makes you want to do so?– psusiFeb 20, 2014 at 17:58

1Then install Windows... it will take care of formatting the drive.– psusiFeb 20, 2014 at 18:06

How to install Windows without a cd would be an entirely different question, and off topic for this site.– psusiFeb 20, 2014 at 18:40

You can't if you want to continue using ubuntu. /dev/sda1 is your main partition and it cannot be changed to another file system without reformatting.
You need to use a live cd or another OS you have installed on your hard drive you reformat it, but you can't do it from inside ubuntu.
open terminal and type
sudo umount /dev/sda1
