Q: How to create bootable USB drive for a PC on a Mac?

On a Late2013 rMBP, you can use the ISO (from the DVD) to create a USB which contains both Windows installer and BC drivers.

Please see How to install Windows using Boot Camp - Apple Support and Boot Camp: Creating an ISO image from a Windows installation DVD - Apple Support.

On a Mac create an ISO from the DVD and put it in a folder. Run BCA (Bootcamp Assistant) and use it to create a USB2 which will contain both the ISO and BC drivers. Uncheck the last "Install/Remove..." option, if you do not intend to install Windows on Mac.

Macs have no read-write NTFS drivers (Apple provides a read-only drivers), so the partition on Macs created by BCA is FAT, which is converted by the Windows installer to NTFS.

Please also see https://help.apple.com/bootcamp/mac/5.0/help/#/bcmp173b3bf2 and http://imgur.com/a/DuGxr#0.

The USB2 has an AutoUnattend.xml which will silently install BC drivers, but these drivers are intended for Macs to support Mac-specific hardware.

There is no way to deselect it on a Mac. Are you planning to use the USB2 flash drive to install Windows on a Mac or on a Windows PC?

If you need to use it on a PC, use Rufus USB tool (https://rufus.akeo.ie) or https://technet.microsoft.com/en-us/library/jj200124.aspx and you can avoid BCA putting BC drivers on the USB. This will give you a clean USB2 without any Mac drivers. You should use the two links and the ISO on the PC directly, instead of creating it on the Mac.

Just use one of the two links and put the ISO on the USB2 drive. Do not use Bootcamp Assistant. Rufus should work much better since you will not have the diskpart executable (it is Windows only). Do you have Bootcamp/Windows on your Mac?

You can use https://www.winehq.org to run Windows programs on the Mac.

Hey there, this is so late, but maybe will be helpful for somebody.

You can install your iso to VirtualBox and then write to USB drive from windows.
