I've recently removed the Windows partition keeping Ubuntu as single OS. The way I did it was through an Ubuntu Live boot-drive, using the Try Ubuntu option. In Gparted I simply removed the referred partition. This is what Gparted shows:

/dev/sda1..fat16....39.19 MiB

unnallocated..unnallocated..281.78 GiB

/dev/sda4..(KEY)..extended..183.94 GiB

../dev/sda6..ext4..180.03 GiB

../dev/sda5..(KEY)..linux-swap..3.91 GiB

unnallocated..unnallocated..1.02 MiB

My problem is that I can not expand my ext4 partition. My goal is to make the unallocated space usable. Can anyone help me?

I would like to clean up this partitions too, keeping just what I use.

Your /dev/sda6 partition is a logical volume inside the extended partition /dev/sda4.

Extended partitions are like containers. They are needed, because there are (were?) only 4 primary partitions allowed at one disk. So somebody invented the extended partition, that can replace one primary partition and contain any number of logical partitions inside.

So now the reason why you can not enlarge sda6 is, that the container sda4 is full. You have to enlarge the extended partition first (therefore you might have to unmount all containing volumes (sda5 and sda6) and the extended partition itself (sda4)). Then, when you have free space inside the container, you can enlarge the partitions inside the container, to cover that new space.

Do you need more explanations or could I help you?
