BootCamp Question

Hello,

I will be installing Windows 8 from an ISO and I have read https://help.apple.com/bootcamp/mac/5.0/help/#apdecf0e4b6-b472-438d-881e-57c230b 1c250. I only have one USB Drive (16 GB) for installing it. When I download the Support Software, can I put it on the same drive as the Windows installer?

Thank You
