After struggling a little bit how to burn windows iso from Mac, I got proper right to do it. Basically, forget to just run dd, it won’t work. At least, didn’t work for me. In fact, all I got when I ran dd command was a faulty usb burned with iso files unable to start the installation from one laptop. So, I had to recover the usb with:
* sudo dd if=/dev/zero of=/dev/disk4 bs=1024k count=2
After that I was able to manage the usb from “Disk Utility”.
You’ll need a:
* windows iso file
* unetbootin for Mac
* usb ready for action
What I did was:
* First, open “Disk Utility” and format again the usb with MBR selected
* After that, open the unetbootin, select the iso and burn the usb.
This was the key to success in installation. I setup usb boot from laptop’s BIOS and then all worked like a charm.
