Resizing

[Stephen]

Hello I'm using Ubuntu 10, 11. I originally set it up in a 40gb 
partition on a windows xp drive. I wanted to give more space to the 
ubuntu partition.
I shrunk the windows partition by 30 gig, and tried to make the linux 
partition larger but it wouldn't let me because I couldn't unmount the 
partition.
So I booted from a live disk and started gparted. All I could do was 
shrink the linux partition it wouldn't let me make it larger.

I am wondering if there is a way I could do this???? I don't want to 
re-install ubuntu.

Thanks in advance;
Stephen
