i did not realise that I needed more space back then. I have almost no space left, I resized the windows HDD from windows. Now I have 15 gb unallocated space, I want to extend to my ubuntu partition.
How do I do it properly?
EDIT: I created a bootable iso with rufus (16.04 iso) and ran it and then clicked "Try ubuntu" but i still cant increase the sda3 gparted picture from usb try ubuntu
EDIT EDIT: Swapoff did the trick!
