Creating a partition isn't hard. Restart with command - R held down and open Disk Utility.

 

Step 1 - select the top level hard drive.

 

Step 2 - select the Partition tab.

 

Step 3 - grab the //// to slide the partition up to make room for a new partition.

 

Step 4 - select the vacant space and hit the + sign. 

 

Step 5- Mac OS Extended (Journaled) and add a name.

 

Step 5a, click and select GUID.

 

Then Apply.

    Back up your data, choose Utilities from the Finder's Go menu, open the Disk Utility(or the Boot Camp Assistant if you'll be installing Windows), and partition the drive. If you use the Disk Utility, click on the entire drive in the sidebar.

    Do you want to install Windows, or just have Mac OS X partitions named C and D ?  Can you give more information and what you intend to use the C and D partitions for.

     

    NOTE:  Mac OS X does not use drive letters.  File systems have volume names, which you can rename to anything you like.

     

    If you want to actually install Windows, then follow Neil's advice

    <How to install Windows using Boot Camp - Apple Support>

     

    If you just want additional partitions with names such as C and D, then you do this using Applications -> Utilities -> Disk Utility.


    STRONGLY suggest you make a backup (even better 2 different backups - maybe Time Machine and Maybe SuperDuper or Carbon Copy Cloner backups) before you attempt to repartition your boot disk.  When you are ready, Google for "Mac OS X Partition" and you will find multiple sets of instructions for doing this.

     

    If you are partitioning an external disk and there is nothing on it yet, or you do not care what is on it, then if you are careful to select the right disk via Disk Utility, then there is less risk.

     

    NOTE:  I rarely partition to separate my Mac OS X from my data.  At work, I do have some external disks where I partition it so that one part is where I make a SuperDuper bootable clone and it is sized to match the boot disk, and the rest of the storage I use for other backups (at work I do lots of backups either of my iMac, or my Macbook Pro to my iMac, or for other systems I use at work where I do not want to loose things I'm working on).

     

    Or I may create a partition where I might install the next version of Mac OS X for testing, before deciding if I want to switch over or not.

     

    Othewise I tend to not partition.
