I want to create a fully automated windows setup CD which can partition and setup windows. I tried to use Gdisk whcih can create partition(s), without reboot the computer, but the problem is I have to specfic how many mb for each partition. If I have a 20g hdd, I can simply create 2 10g partitions and setup windows with a simply batch file, but it will not work if i can a 40g or bigger hdd. I do need to use partition magic after for the remaining space. I want to create a CD can work any computer. I want to have a self boot CD can create like 2 partitions like 50/50 of the hdd, and setup windows with a unattend file without pressing any key. I also read a document I can use a hex editor to create a file to automated fdisk to create 2 partitions, like 50/50 of the hdd, no matter what the size of the drive. I have reboot the computer, in order to finish the whole partitioning process, how can resume the windows setup without type the setup command after reboot. Is that anyone can help?
