Backtrack 5 r3 hardrive partition/installation (Dual boot Win.7)

[Destro777]

Okay, let me preface this by saying I am a complete noob when it comes to linux. period. That's why I am here.
I am trying to install Backtrack 5 r3 on my Hp G62 Notebook PC (64-bit) running Windows 7. I have been able to successfully boot backtrack from a live cd. Unfortunately I simply can't figure out how to install it to a partition instead of wiping out Windows 7. I have Google'd non stop for about 2 days now trying to find out how and there are a lot of tutorials which I have read and even youtube videos that make it look like its a breeze but they haven't helped. So far I have created I 25 gig partition that I want to install backtrack to (figured this would be enough since its not going to be my main OS). here is a snapshot of my setup:

After setting up that partition I restart (once back into windows 7 to make sure everything is working fine then into backtrack from the cd)
Once in backtrack I click on the Install backtrack icon on the desktop and get through the first 3 steps before seeing this:

Then I go to specify partitions manually because I dont want to erase my HD and I get this:

Now I dont know if this is because I did something wrong along the way but I cant find my 25GB partition I made although I assume its in there with /dev/sda4 (possibly showing up with the RECOVERY (D drive?) anyways I dont know what to do at all from this point. I also noticed that the "new partition table..." option at the bottom is only available when i'm on the /dev/sda1 drive thing and when I am on any of the others my only options that I can click are the ones shown here:

Please if anyone has any helpful information that would be greatly appreciated!!
