How can I repartitioning Ubuntu using "unallocated" spaces at random parts of my hard drive?

Question

I have this unallocated space before my root partition and GParted doesn't let me add it to my Ubuntu partitions. I am running Ubuntu from a USB drive. While it lets me add it my Windows partitions. What can I do to increase my partition size (selected in the picture)? GParted Screenshot

You have to create partition table at first and then mount the filesystem to the OS. If you mean that you want to shrink your root partition you should use something like resize2fs utility. You can do the same with GParted while booting from liveCD.
