I have tried all kinds of variation of the dd command with some suggestions to format with fat and some ntfs, use isohybrid then ensure to sync at the end of the dd process; yet none of those techniques work.
The other day, I was referred to a product called mkusb and it worked beautifully. It had different options to create Linux or Windows images. I guess there are different implementations of the bootable usb when it comes to the different OSes. Also this product is implementing dd commands in the background so obviously these developers knows the parameters and proper provisioning processes to make it work. I will dig into their codes to figure out what I did wrong in the near future then repost of my findings.
