    Missing Operating System message while booting


    Hello guys.
    I just erased my whole disk drive and I created a single unpartitioned space to my hard drive using GParted(
    http://gparted.org) usb stick (which proves that this system can boot from usb).
    The problem is that whenever I try to boot from my usb drive (fat32) to try either windows 10 technical preview or windows 8.1 the system bypass the usb stick and displays the message Missing Operating System (because it arrives at the 3rd boot option, the internal hard drive - 1st is external device and 2nd is the optical disk).
    Any ideas?
    Thank you.

    You can't make a bootable usb of any version of Windows only linux, you CAN though make an install disk.

    Use the bootcamp assistant - just take the first option to make the USB and that should work..

    Bootcamp assistant is on your mac, not on the PC... You can use it to make a bootable USB from your Windows 10 ISO.
