Hello all. My goal was to use free hyper-v core to make a simple nas. Why this = to avoid authentication problem (most linux distro arent stable for authentication). The problem was that if i use the latest free hyperv iso, i cannot use it on USB like on ms site or altaro site I have 2012 server iso, and i use it i cant boot on usb. i've seen recent post un multiple forum on person that experienced usb problem with recent ms update. So i search the FIRST hyperv 2012r2 iso that microsoft release (the one without update integrated). I thanks you for your response.
