well if you want to run ghost for dos then it must be a fat32 drive. you can partition your drive to make a 10gb segment at the start of the drive be fat32. you need to load a MBR to the drive, you can do this with any number of tools such as grubinst_gui and then copy there premade grldr to the drive. all this can be done from with in disk part and using the bootsect comand in windows 7. i would recommend using the tools if you are new to partitions and file systems.
