I know the regular Ubuntu install will automatically resize your hard drive for things like this, but I don't remember if Ubuntu Studio does. If not, and you don't have extra free space on your drive, you may need to first launch Ubuntu from a live CD and use the partitioner editor to shrink the size of the regular Ubuntu partition to free-up space for Ubuntu Studio. (It isn't possible to resize a mounted disk, which is why you need to use the live CD) Once you do have the space, just install Ubuntu Studio in this free space, and at the end of the install, Ubuntu Studio should recognize whatever other OSs you have, and set-up your GRUB menu appropriately. When this is done, you'll be presented with your choice of OS when you start up your computer.
