Can I install and use Windows on an external USB 3 drive in Boot Camp I'd like to try Windows 10 Technical Preview before it is released for purchase.
I am curious and have never used a windows based machine before.
Question: Is it possible to install and run Windows 10 Technical Preview under BootCamp
You can install windows via BootCamp on an external drive. However to install a newer version of windows that BootCamp doesn't support you need to first install a supported version then upgrade inside of windows to a newer version. My best suggestion though is to install via a virtual machine.
