Title: Auto-select the first disk devices instead of statically using /dev/sda

Dynamically select the disk to install, choosing the first one that shows up on the system. This allows the installer to continue on systems that don't have a /dev/sda, such as qemu-kvm VMs with virtio that sets it's disk as /dev/vda.
