Unable to install Windows 10 via Bootcamp on late 2013 iMac?

I'm using an iMac (27-inch, Late 2013) 3.2 GHz core i5, and trying to install Windows 10 via bootcamp. I've downloaded the Windows 10 iso and got an external 32GB USB stick for the install disk (formatted in exFAT). When running bootcamp, it however prompts with the error "Your bootable USB drive could not be created - There is not enough space available on the disk". Would anyone be able to kindly advise where I might have went wrong?

Thanks for the pointer Loner T, much appreciated :)


I've been researching some forums and am glad to inform that I have successfully got Windows 10 up and running via Boot Camp!


The reason I was getting the insufficient space error was because Boot Camp was trying to create the bootable USB drive formatted in FAT32 (which has a 4GB limitation), whereas the Win10 ISO is in the ~5GB range. I followed "Answer #1" in the url below to manually create a bootable Win10 USB drive, formatted in ExFAT. Once done, I ran Boot Camp Assistant and only selected the option to install Windows. From there on it was pretty smooth sailing.

FYI I am still running macOS Sierra 10.12.6.


Thank you and good luck all!
