I have two hard drives loaded with windows XP Pro and have them installed in one case. I want to be able to select which hard drive (system) to boot from on start up by entering the BIOS or selecting from windows. I do this now by moving the controller cable to the drive I want to boot from. One condition, the hard drive I didn’t boot from must not be visible to the system. I connect to a network and I don’t want the other drive scanned or seen by the network admin.
