Description of problem:
When using the UI wizard to create a new Windows VM, it is not possible to attach disks.
Creating a Windows VM using PVC will fail.

(works with RHEL)

Version-Release number of selected component (if applicable):
OCP: 4.4.0-rc.1
CNV: 2.3 (operatorVersion: v0.26.3)

How reproducible:
100%

Steps to Reproduce:
1. Create a DV

apiVersion: cdi.kubevirt.io/v1alpha1
kind: DataVolume
metadata:
  name: win-16
spec:
  contentType: kubevirt
  pvc:
    accessModes:
    - ReadWriteMany
    resources:
      requests:
        storage: 38Gi
    storageClassName: nfs
    volumeMode: Filesystem
  source:
    http:
      url: "http://x.x.x.x/files/cnv-tests/windows-images/win_16.qcow2"2


2. From the UI, select "Workloads" -> "Virtual machines" -> "Create Virtual Machine" -> "New with Wizard"

3. General screen - enter the following:
-source: disk
- Operating system: Windows Server 16 (Could be any Windows OS)
- Flavor: medium (could be large)
- Workload profile: server
- Name:

4. Network Interfaces - continue
5. Disks screen - >"Add disk" - enter the following:
- Source: Attach disk
- Persistent Volume Claim: select the above-created PVC

Click "Add"

Actual results:
Windows VM from Wizard, using PVC, cannot be created.
- "Disk with this name already exists!" error appears in the "Add Disk" screen
- The disk is added in the Disks screen
- If the disk is selected in the "Boot Source" dropdown menu and "Next" is clicked, the following error appears:
=========================
Required fields not completed
Please select the boot source.
=========================

Expected results:
Disk can be attached, VM can be created.
