From How to install Windows using Boot Camp - Apple Support,

For some Mac models, you also need a blank 16 GB or larger USB flash drive

The USB is used for

1. Downloading BC Drivers, or,
2. Building a USB Installer, if you Mac supports it.

On a 2010 Mac, you will need to install Windows using your Optical drive.
