Complex dualboot

[PCman13]

Hello everybody,

I have the following situation: I have a computer with one hard drive of 500 GB. I have included a screenshot of gParted. I have already resized the Data partition. That went a little bit wrong, I made it too much smaller. Now I want to do the following things:

-Enlarge the System partition [32gb] to 64 gb
-create a new partition for Ubuntu (64bit) of 64 gb
-use the remaining space for the Data partition

I have no experience with this, and I don't exactly know how to do it. Can anybody help me please?

note: to resize the partition, always do it on unmounted one (boot on live cd for example)
