hi at all!
I have a big problem with OMV:
I'm trying to install it on my new PC with asrock h170M pro4S, intel g4400 e and 8gb of ram.
When i select the keyboard lenguage, i always have an error telling me that I don't a CD drive, so OMV doesn't know where to find drivers. It tells me to go after that point, but when I try I have error again!
How can I install OMV? 
edit: resolved thank to rufus and usb 2.0
