install gparted
using the following command from a terminal(ctrl+alt+t)
sudo apt-get install gparted
Once installed, start gparted. it will ask for authentication. Enter you password and you will be able to see and resize your HDD partitions.
Exercise caution and take backups before doing these activities.
Also note that you can't (and shouldn't try to forcefully) alter partitions with mounted file systems. It's also impossible to unmount file systems mounted at /
, /usr
, /var
or similar, since they're crucial for the running operating system. Even /home
is difficult in graphical mode. If you want to modify those, use the Live CD, DVD, or USB drive. The Ubuntu ISO comes with gparted tool in the Live session. So you don't even need to install it. Just open it and alter the size of the partitions.

Press the "Super" key (windows key) and type GParted. Open the GParted Partition Editor.
In the GParted dropdown menu, you can select which device you want to partition, format, etc.
