    I can't for the life of me make a bootable USB drive with Windows 10 on it from OSX. Seems Disk Utility has changed and Bootcamp assistant does not have it as an option.

    When I try to "restore" the USB drive under disk utility I get "Could not validate source -invalid argument"

    Any other ideas or free apps I could use to do this?

    Sounds like a dysfunctional drive. Can you format it to NTFS?

    I couldn't get it done either using dd - I ended up borrowing a friend's windows computer and using the usb creator from Microsoft. I read elsewhere that you can try to use a parallels trial and do the same thing on your Mac.
