So, I have a PC that does not have an optical drive, but I do have a Windows 7 DVD and my Macbook Pro. How do I go about creating a bootable Windows 7 USB stick in Mac OS X?! I've tried a ton of things so far including: Making an .iso of the DVD using Disk Utility, then using Bootcamp Assistant to create a bootable USB. I boot from the USB on my PC and get a black screen with the 'No Operating System Found' error... Any idea what I'm doing wrong? Any one else successfully made a bootable USB windows 7 disk in OS X?
