So I had an old partition that I deleted, and now moved all my stuff to the new one. Now I am out of space, and I want to resize it to fill the whole hard drive.
But Disk Utility wouldn't let me resize the partition! It is grayed out.
So…
I boot off of G-Parted Partition Editor, and sure enough, I couldn't resize the partition! I could only make it a bit smaller to the few megabytes of remaining space.
What is wrong, and is there a way to fix this?

As already mentioned, the free space is before the start of your partition. You can't grow a partition from the start - you can only expand it from its end.
You can try something like this:
There are a few other options as well as Carbon Copy Cloner, but it has worked well for me in the past, and will make the target partition bootable.
