This happens because the Windows Operating System does not have the appropriate drivers (VirtIO driver) to read the disk that has the operating system installed on it.  

 

In a nutshell:

1- Download both VIrtIO and Windows ISO to the image store in the cluster (you can use prism “image configuration” or prism central Explore->images->add image”)

2- Mount both VirtIO drivers and Windows ISO as CDROMs for the guest VM with problem.

3- Power on the guest VM booting from Windows ISO CDROM, you will see an option called “Troubleshoot”

4- Choose the above option and go to command prompt

5- Get the list of mounted disk drives and navigate tot eh drive where VirtIO resides

7- Load the drivers: “drvload vioscsi.inf”

8- see that drivers are mounted now “wmic logicaldisk get caption”

9- exit and reboot guest Vm

10 After you login, go ahead and install the VirtIO MSI package

You are missing the most important step, injecting the drivers with dism into the os.

dism /image:{drive_letter_from_above}:\ /add-driver /driver:vioscsi.inf
