Create a Bootable Windows USB from a OS X to work on a PC

What I need to achieve is

1. Create a Bootable USB drive from Windows 7 iso image using a Mac running.
2. Use the flash drive to boot and install windows on a PC (not Mac)

What I'm looking for is an app like WinToFlash but one that can run from OS X. This app make a bootable flash drive from a Windows iso image. I found a mac alternative to WinToFlash a while ago, but I don't remember the name.

All I can find is questions about making a bootable usb from a mac to a mac. I want to repair a Windows PC that doesn't startup but I have a working Mac computer, the target computer is a PC (not Apple).

A PC can't boot from a USB created with bootcamp which have MBR based BIOS.

UNetbootin doesn't seems to work with Windows iso's just Linux iso's.

P.S. the target PC have BIOS, it doesn't have UEFI.

Solution 1:

Bootcamp can create a USB for PC. Just only check the "Create a Windows 7 or later version install disk" checkbox. A similar question from How to create a Windows 7 installation USB from OS X? shows that Bootcamp has the "ability to create install USBs" for Windows.

Solution 2:

Have you tried using UNetbootin with the Windows ISO? According to various references online it should work (although that was using the Linux and Windows versions).

Several years ago I created a Windows 7 boot USB using UNetbootin but I can't remember if it was created using OS X or a Windows virtual machine.

Solution 3:

Please use following link, I have successfully created bootable usb for windows from mac.
