How to get pass "Downloading Windows support software" in Boot Camp Assistant? I am having a problem in my Windows laptop, so I need to make a Windows 10 bootable to repair/restore it.

I am using  a Mac for making the bootable for the PC.
I downloaded the windows 10 .iso file and started bootcamp to make the bootable.
The process seems to get hanged at "Downloading Windows support software" step. 
I tried keeping it overnight, no change in the progress bar. Just stuck there at 50/60%.
The problem got solved by formatting the disk. 

I formatted the disk first in FAT format. Then the Boot Camp Assistant worked easily.
