Hi, i am using RT7 lite to create a base windows 7 64bits image. I need to create 3 partitions. I do not see any option in rt7 lite to create new partition. What i did is to modify Autounattend.xml file in the root directory before creating Bootable ISO image to add the 3 partitions. Every part gets executed except the part to create/modify the partitions.Anyone knows how to make RT7 lite create more one partition. Your HELP highly appreciated
