You need to manually add PreBoot drivers to Deployment Solution 6.9 and later or Ghost Solution Suite 3.x.
There are two versions of the Boot Disk Creator included in Ghost Solution Suite.
Start by navigating to the appropriate folder location, and open the platform folder that you are adding drivers to. For example, "Winpe5" and "x64" when using the 64-bit Winpe5 for your boot images. If you have a mix of x86 and x64, you need to perform these steps for both subfolders.
CAUTION: Each driver directory should have at least an .INF file, a .SYS file, and a .CAT file. If a driver directory does not include these files, then the driver is incomplete and will not work.
