Lost partitions after a botched Windows install attempt via Bootcamp

I tried to install Windows 8 using the bootcamp assistant, but when I got to this screen,

The BOOTCAMP partition created by bootcamp wouldn't accept the windows install. Meaning, I reformatted it, and normally the little sun button "New" would then allow me to proceed with the Windows install.

I thought it was very weird so I instead deleted the partition, which turned into a 47.3Gb of Unallocated Space.

I tried formatting said unallocated space which created a bunch more partitions, but ultimately the same problem persisted: Can't install Windows.

In OSX, the Disk Utility wouldn't let me actually delete or remove the partitions so I went back to the Windows install menu and turned all the undesirables into unallocated space.

Here's what my Disk Utility looks like now:

As you can see there's some purple stuff at the top and some dark-grey stuff at the bottom, which I imagine represents free space?

Finally, here's a diskutil list readout:
