Cannot increase Ubuntu partition with GParted. Maximum size

view story

http://askubuntu.com – Before I started this, I went into Windows 8 and reduced it's size to allow roughly 10GB of unallocated data. I want to increase Ubuntu 12.10's partition to fill that void. I ran Ubuntu (Trial) from my CD as told to in multiple tutorials and ran GParted. Here's my GParted screen: http://i.imgur.com/8lyzYWF.png?1 But, when I try to right click and "Move/Resize Partition", it does not allow me to increase the partition size any more. It's "max size" is what it's at currently. How do I make it take over the unallocated space? sda1 = System Reserved sda2 = Windows 8 ext4 = Ubuntu 12.10 (HowTos)
