|"Is that because my dual boot has a built in camera?"|
There's no need for all that hassle, there's no need to install the Canon software, and there's no need to fiddle with a cable to connect your camera to the computer.
Just buy a memory card reader.
Plug the reader into Mac or Windows PC.
Remove card from the camera.
Insert card into card reader.
Open folder containing pics on card.
Select and copy pics to hard drive.
