Pretty sure that error is referring to the live USB stick you're booting from and can be ignored. You can also start GParted through main menu (instead of terminal command) by going to Menu -> System -> Partition Drives (or GParted).
Sounds like you're planning to delete all of the partitions within the extended partition /dev/sda4 and start over. If so, please NOTE from your original pic that the NTFS partition /dev/sda5 shows it's got over 6GB of data on it. If any that is important, make sure you copy the data somewhere else before you delete that partition. In Windows, I'm guessing that /dev/sda2 is your "C drive", /dev/sda3 is your "D drive" and /dev/sda5 is either "E drive" or some other letter designation after "D". So you've got your normal "C drive" and what looks to be two other partitions for data or other things in Windows. If that's what you want again, make the new NTFS partition first in the extended partition, then leave rest of space unpartitioned/unforumatted. When you choose the install "Alongside Windows" option, the installer will then use the empty space and make the root and swap partitions for you.
