Testing partitioning over old windows installation

Similarly to the other wiki articles for quickly testing things. This script should help you test installing over a windows installation.

Requirements

1. Download and place the following Windows 10 ISO in your ~/Downloads catalog: https://www.microsoft.com/software-download/windows10
2. Download and place the following virtio-driver ISO from fedora in your ~/Downloads catalog: https://github.com/virtio-win/virtio-win-pkg-scripts/blob/master/README.md

Once running, select amd64 -> win10 to load the disk driver. (I'm aware that you could use qemu to boot using IDE drives, but this will specifically test SCSI based drives).
