Your disk has five partitions. This isn't supported for Boot Camp disks. You can only have four: EFI System partition, OS X, Recovery HD, BOOTCAMP. You have an extra partition due to the resize attempt, an additional HFSJ volume it appears.


As mentioned on another thread that's pretty close to identical to this case, there is a distinctly non-standard, not highly advised, work around that will let you at least boot Windows, and also share one of the other partitions.


You'll need to use gdisk* to create a new hybrid MBR from the recovery/transformation menu, and add partitions 4 and 5. So you'll type 4<space>5<enter> into the proper field when prompted what partitions you want to add. This will allow you to see the partitions Data and BOOTCAMP from within Windows (and OS X also, of course). But you will not be able to see the primary Macintosh HD from within Windows. Make sure when asked that you do not set GPT partition #4 (MBR partition #2) as bootable. But do make GPT partition #5 (MBR partition #3) bootable. Then use the w command to write out the new partition tables and reboot.


* This is a command line only application, but functions in an interactive mode. So you type ? <enter> to get the listing of the main menu, and various commands have multistep processes that you're prompted for.
