Some time ago I created a windows partition on my MacBook using Bootcamp.
At the time I set it at just 10 MB.
Now I want to expand the size of the partition.
Is there a way to re-size the existing partition?
Or do I have to start all over from scratch?
If the latter, how exactly do I do that? Do I need to first erase the existing windows partition, and then create a new partition with a larger size?

Resizing a Boot Camp partition is not officially supported by Apple. You would have to start over again. This is one of the benefits of running Parallels or VMware Fusion. If you are going to start fresh, I recommend moving to Parallels or VMware Fusion over Boot Camp, unless there is a specific need to use Boot Camp. You also get the benefit of being able to backup your Windows virtual machine, drag and drop functionality, and not having to restart the MacBook each time you need to run Windows.

To start over with Boot Camp, you would need to do the following:

-De-authorize any apps such as Photoshop, iTunes, etc.
-De-authorize the Windows install
-Delete the Boot Camp partition with the Boot Camp Assistant
-Create a new Boot Camp partition
-Install Windows and authorize
-Reinstall all Windows applications and authorize

Make sure you backup any important documents in Windows before you proceed as they will be lost when you delete the partition.
