error creating efi partition with powershell

Hello. I have a problem when trying to create the partitions for installing windows 8 on a GPT disk. The error happens when trying to create the efi partition. The command that is in bold. The error reported is:

Format-Volume : No matching MSFT_Volume objects found by CIM query for enumerating instances of the ROOT/Microsoft/Windows/Storage/MSFT_Volume class on the CIM server, that are associated with the following instance:

MSFT_Partition (DiskId = "\\?\scsi#disk&ven_msft&prod_virtual_dis..., Offset = 315621376). Verify query parameters and retry.
