Has anyone seen that before? Never used Server, but I use ESXi and I know what your issue is: Mass Storage Drivers, you need to make sure the Critical Device Database is populated with the driver in the destination system, such as an LSI SCSI or SAS and that that service start type is set to "boot". Install the driver then add it to the crit dev db in: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\ Follow one of the necessarily existing PCI#VEN_xxxx&DEV_xxxx for syntax. Change the Service Start Type: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nnnn >From probably 4 to 0. http://support.microsoft.com/kb/103000 I use the LSI SAS for everything... jlc Ps. I think the current version of ESXi allows an ide controller to avoid this...
