Does the machine you are imaging have a SATA hard disk? If so, are you setting the hard disk to legacy mode in the bios as PCDOS does not recognise hard disks.
What operating system are you imaging? If Win 7 then there are two partitions you need to image.
If you are creating a WinPE boot environment from your version of Ghost Solution Suite then you need to add VISTA 32 bit drivers regardless of what operating system you image as WinPE in GSS is based on the Vista kernel. You will need to add drivers for both the NIC and the SATA chipsets and then make sure the drivers are selected before you create a new boot image.

Frankly, PCDOS is a PITA when it comes to modern hardware so WinPE is really the way to go.
