This will be because there is no unpartitioned free space to create the new partition in, if you wish to resize a partition to create free space you'll need a third party app like Partition Magic to do so, otherwise your Windows installation may be damaged.
On the other side, if you back up all your data then delete and receate your partition (but smaller for XP) then reinstall you can then from within XP create a partition on the unpartitioned space for Vista through Disk Management (remember the minimum for a Vista partition is 15GB so be sure to leave at least 16GB free when you make your XP partition, I would recommend 20GB at least) You can then install Vista to dual boot.
Vista alters your MBR to the new BCD method and if you wish to alter the boot order etc try this little app EasyBCD
