STOP code 0x75640007 comes from the App Layering filter driver.  It specifically means that all of the required layers were not mounted by Windows within 10 minutes.  Since those layers should appear instantly when Windows boots up, we assume there is a problem and blue-screen so the system can try again.

The most common reason for Windows to be unable to surface the layer disk is a policy or software that blocks access to removable devices.  These policies are usually designed to block access to USB drives to prevent corporate espionage.  However, virtual disks from most hypervisors are also set as removable in Windows, which allows the hypervisor to add and remove them without rebooting the guest OS.  Technically, both the boot disk and the package disk are removable, but Windows can't be blocked from accessing its own boot disk.  So the policy only blocks access to the package disk, which means App Layering cannot access it.  We wait 10 minutes for it to become visible, and then we give up.

The only solutions are to remove the policy (or configure the software to stop that restriction), or figure out how to white-list the extra disks.  If this is not possible, contact Support and we can look into software that might be able to change those disks to be non-removable.
