I have a Generation 2 Windows 2012 R2 VM in SCVMM 2012 R2 with RU8. I am able to boot the VM without issue, but once i have it patched and run the template creation process for this VM i get the following error:
Error (13206) Virtual Machine Manager cannot locate the boot or system volume on virtual machine "VMNAME". The resulting virtual machine might not start or operate properly.
I have checked and the Boot order is SCSI 0,0, which should be correct.
