"your bootable usb drive could not be created" issue when trying to run boot camp assistant
I have downloaded the latest windows disk image from https://www.microsoft.com/en-gb/software-download/windows10ISO
I am using a new SanDisk 32GB USB drive where the windows install setup should be saving. However, I get the following error:
"Your bootable usb drive could not be created. There is not enough space available on the disk." There should be enough space as it's a new empty 32GB drive and the boot camp requirement is only for 16GB.
How do I resolve this error so that I can install Windows on my Mac?
MacBook Pro 13″, macOS 10.13
