gparted

Hi, download ubuntu then use startup disk creator to make a bootable usb stick, then you can change your partitions using the usb stick.

Here is a guide you should read before you try to change them, it is a risky task.

You should always back up everything first.

Hi, that is true but gparted is not on windows, only ubuntu so you still need to use jump drive.
