this is an image of the disk manager's sight of the array setup after creating it.
the xp-150 drive is where the OS is located now. It is the active partition and os.
the other volumes[xp-raid] works fine and is quick[using the VOPT hard disk health test].
It is not possible[according to all info available] to have a second OS work[boot up or have access to] from the raid volume other than the one that is already present and working.
what exactly is the point then of having this ''software raid'' if one can not use it and have an OS work from within it?
very frustrating when one doesn't know.
