This should be a trivial one; unfortunately, it isn't. I've been trying to create a bootable USB stick for Windows 10. The bootcamp tool seems easy to use, but it always stops with the following message:
Your bootable USB drive could not be created. There is not enough space available on the disk.
I've tried with too different USB sticks, a KINGSTON USB 2.0 16Gb stick and a Corsair USB 3.0 32Gb stick. I first tried to do this on MacOS 10.12, no luck, and then took this experience as an incentive to upgrade to MacOS 10.14, yielding the same result.
The Windows version I downloaded from Microsoft is the newest October update. The filename is:
The bootcamp tool doesn't allow any customization of the process, I don't think there is anything I could do different. I have difficulties to believe that bootcamp is just broken.
I've also tried to create the USB stick both with dd and Etcher, both yielding no error, but the stick wasn't bootable in the end. Etcher even warned me about this and suggested to use bootcamp instead. Instructions how to make the USB stick bootable would be welcome.
