Ubuntu – How to expand a partition into non adjacent free space using GParted

Note: You'll have to do this from a live USB/live DVD.

CAUTION: This will wipe data off the windows partition(s), and possibly (although very unlikely) your Ubuntu ones as well.

Open up GParted (click on dock, type in "partition"), type in your password. Right click on your Windows partition(s) and click on delete. Apply changes. After that right click on your Ubuntu partition(s) and click on re-size/move, re-size your partition by dragging either side of the bar. Move the partition by dragging the bar itself. Apply changes, and you're done. Reboot into your main Ubuntu, and enjoy.

As for the /home and /boot, read these:

making /boot partition after install

making /home partition after install

Uwe Plonus's explanation is correct, but gives no solution to your problem. Here's the solution:

1. Boot a Linux emergency disc. (The Ubuntu installer in its "try before installing" mode should work fine; or you can use Parted Magic or something similar.
2. Launch GParted.
3. If any of the logical partitions (those with numbers of 5 and up) are locked (typically with a little key icon, as in your screen shot), unmount them. There should be an option to do this when you right-click the icon. Your swap partition is the only one that's likely to be so affected, and its unmount opiton is called "swapoff."
4. Right-click the extended partition (this is easier in the list in the bottom pane of the window) and select the option to resize the partition.
5. Adjust the size of the extended partition to fill the available space.
6. Create your new partition within the extended partition, which should now contain the unallocated space.
7. Click the "apply" icon (typically a green check-mark).
