i'm using the newest version of acronis disk director suite 10. actually i have two primary partitions on my hdd1 although i've just one operating system installed. before i install a second i wanted to activate the os selector in order to hide the partition where already a system is installed. i wanted to prevent that this partition is shown when i've set up the other system. now my problem: i can't open os selector. is this because i haven't installed a second system?
