Ubuntu – How to resize partitions


Previously, I have installed Windows 7 on my 320 GB laptop with three partitions 173, 84 and 63 GB each. The 63 GB partition was where the Windows was installed. The rest were for file containers.

Now I changed my OS to Ubuntu 12.04 LTS. I installed Ubuntu by replacing the entire Windows 7 on the 63 GB partition. The rest of the partitions remain as an NTFS Windows partition and I can still access them both (the 173 and 84 GB partitions).

Now I want to change the two partitions of Windows into an Ubuntu format partitions plus most importantly, I want to extend the 63 GB partition to more than a 100 GB because at the moment I am running out of disk space. Whenever I try to install any application, especially using wine, it always complains for a shortage of disk space.

How do I do the extending activity before I entirely format my laptop again and lose all the important files on my partitions?

(Step 0:) Back up anything really valuable. This is a pretty tried and tested formula but things can go wrong. A power cut at the wrong moment could really ruin your day if you haven't backed up.

  1. Boot to a LiveCD or LiveUSB drive in "try me" mode.
  2. Load gparted (should be installed by default, you can apt-get it if it's not)
  3. Resize your partitions (right click, click resize, follow the instructions).
  4. Click apply and sit back while it does the job.
  5. Reboot, taking out the USB stick or CD when it tells you to.
