Most likely it is an issue with the assigned virtual disk controller.
In the VM's settings do the following:
- Make sure the OS is set to Windows Server 2008 R2
- Set the HDD controller type to "LSI Logic SAS"
I'm not 100% sure about the controller type for a converted machine. It could also be set to LSI Logic SAS and needs to be set to SCSI. This depends on how the conversion was done and which OS was set for the source VM.
