Sometimes you get that if you've specified the wrong or an unbootable boot device in the Virtual Machines config menu -- if you click the show boot menu in the virtual machine manager and then when booting the VM you see that screen just type EXIT and you should then see a list of bootable devices. It's not usually "An error".

If you've also specified "virtio" as the type of disk rather than SATA then windows won't load initially since it won't have a disk driver - If you want to use virtio (and it's better than the standard sata / ahci driver) then once you've booted up windows install the virtio drivers from the fedora site - iso is available for direct download. Install on the GUEST of course !!!!. Same for the NIC's -- unless you've got a spare nic on your pc to pass thru to the VM use virtio for the NIC adapter -- better performance than the standard e1000e virtual adapter. If poss try and avoid shared wifi from the host. If you must use wifi then it's better to use a separate usb>wifi adapter for the VM.

If you use a separate physical NIC for networking in the GUEST then you don't need to specify NAT, Bridging or even any NIC at all in the VM's config- -- Just add directly to the GUEST either by USB redirect, add Host USB device or add Host pci device in the config and install any relevant driverson to the guest. Host to guest communication (and vice versa) will work just as llike any other two physical machines on a LAN

I have on my test HOST machine 2 LAN devices so I can dedicate one to the VM. Direct LAN gives network performance almost 100% of the Host. (Use Bridging rather than NAT if you can't add a separate usb type wifi / lan adapter etc) - but that's another story too).
