How to put windows on ubuntu server?

Question

ubuntu

1. I create a virtual machine and run the installation from the image:

sudo virt-install -n windows -r 2056 --disk path=/var/lib/libvirt/images/disk.img,bus=virtio,size=15 -c Windows_7_Ultimate_SP1_BY_OREL_SFT.iso --accelerate --network network=default,model=virtio --connect=qemu:///system --vnc -v

2. I connect via vnc.
3. windows 7 does not see disks.
What to do ?
