Crash on boot through virtio driver viostor on KVM/Qemu

Host: Debian Linux kernel 4.8.0, Qemu 2.8, virt-manager 1.4.0, virtio-Windows-drivers 0.1.126
1. In virt-manager add disk, type qcow2, bus virtio
2. Boot ROS
3. When new hardware wizard appears, insert virtio ISO file as CD
4. Install driver automatically -> "RedHat Virtio SCSI controller" is detected and set up
5. Restart ROS
At boot stage "Loading boot drivers" message appears: "Can't load boot driver 'system32\drivers\viostor.sys'!", after confirming black screen only. Removing the virtual virtio disk does not make the system booting. Additionally restoring a disk snapshot to a status before installing the virtio driver heals the system.
