How to burn Windows 10 ISO to USB? I've been googling for hours; everything I can find either is for Bootcamp or doesn't work.

So, I have a clean PC that I want to install Win10 on; I also have a Mac with a Win10 ISO and a flash drive; how do I put the ISO onto the drive? I've tried using Unetbootin, but the PC doesn't boot from it. 

My Boot Camp Assistant does not support burning ISO's to USB; it just installs from ISO directly.
First, by "flash drive" we both understand external USB flash drive, right? :) If not, then get one :) Make sure it does not contain any important information.


Insert clean USB flash drive into your mac
Start standard Disk Utility
Select your USB flash drive on the left panel
Click 'Restore' button in Disk Utility window
In the dialog window click 'image' button and select your ISO image
From drop-down list in the same dialog window select your USB flash drive
Press 'Restore'


You should get properly prepared Windows 10 USB installation disk.

Hope this helps.
