We will try just the win 7 drivers that shipped with 3.6.3 rather than the
SHA-2 signed FC23 drivers and I'll get back to you. I have a question:
if I try to build a Win2k12 server via WDS, I assume I will have to add
the 2k12 drivers and then remove them again if I go to build a Win 7 VM
as Win 7 will presumably try to pick up the 2k12 driver? Or can they
WDS has a build process whenever drivers are added (e.g., for KVM, VMWare
etc) for available drivers. Do you know when the fix will be available?

It just says: Windows is unable to install to the selected location. Error:
0x80300001 (see attached)

I've tried a variety of different ways to do this, by deleting all
partitions, allowing Windows to create
them again, formatting them etc. I've tried both the viostor and vioscsi
drivers with the same result.
No matter what partition I select (System or Primary) it always produces
the same error.

Any ideas on when the newly signed drivers will be available?

Kind regards,
