i am struggling to make the following scenario to work and had no success... the hardware is 1. SSD drive with 3 partitions that getts assigned as Disk1: - 1st partition hidden and active boot partition - 2nd windows partition - 3rd applications and games partition 2. HDD with 2 partitions that getts assigned as Disk0: - 1st hidden and active windows kit partition - 2nd users folders and programdata the computer is configured to boot from the ssd and thus use the disk1-partition1 as the boot partition. now if i manualy boot from disk0-partition1 (i am using windows assignments for the disks, actually the first disk in my computer is the ssd, and i dont really know why it gets assigned as disk1), i have to start the instalation manually (by running "setup.exe /unattend:unattended.xml") but what also happends is that the boot partition becomes disk0-partition1 the one with the windows kit on. what i would like to know is if there is a method to force windows to use as boot partition the partition on my ssd that is disk1-partition1. thanks
