Why is"Create Single Partition" giving "The disk you specified is not valid", prompting "Preinstallation Task Failed" ?
In running the following preinstallation tasks
Upload Hardware Inventory
Create Single Partition
Format C: as NTFS
Install Vista/2008/7 MBR
... on a Toshiba Portege M400, I am getting the message, "Preinstallation Task Failed" | "Do you want to continue?" with the following in the CMD dialogue box behind it....
Executing diskpart /s create_single_partition.conf
Microsoft DiskPart version 6.1.7600

The disk you specified is not valid.
There is no disk selected.
Executing call format_c_as_ntfs.bat
Specified drive does not exist
I know the preinstall tasks are not corrupt because I am using them in another deployment successfully. I have also used this installation on the same model of computer successfully in the past. In addition, I have tried it on several different M400 computers all with the same result. And finally, I have reset the factory defaults of the BIOS, etc., all to no avail.
The computer is fine - if I open Windows normally and run diskpart from a command prompt and then type list disk, it is listed as 0. However, if I run the Command Prompt from the Kace Recovery menu and type the same thing, I get the message, "There are no fixed disks to show." Why the discrepency?
Can you help me get past this error? Any trouble-shooting opinions on this?
