Running dual boot Windows and Ubuntu 14.04 LTS, want to repartition to keep Ubuntu and replace Windows with CentOS

I googled "dual boot CentOS and Ubuntu" and there is a tutorial for this particular setup, but it assumes the free space on which to install CentOS is already available. Looking at GParted, I'm not sure how to tell what portion of the HDD is Windows and what is Ubuntu. I'm assuming that once I figure that out I can just run the CentOS custom install where it says free space. Is that accurate? Sounds easy enough, but I didn't wanna make any devastating mistakes. Attached is my current partition scheme. Thanks in advance for any advice.

Looks like (can't be sure as it depends on how you use filesystems) sda1 and sda2 are Windows (sda1 the recovery partition). If you have any data you want to keep that is on there, copy it off first, then delete the two partitions.

You then can use the combined space for CentOS. If you are careful - you can reuse the existing linux swap partition for both systems - though if you do suspends/hibernates it isn't a good idea (as that is where the hibernation/suspend data gets saved).
