    I have no RAID option in my boardnot ever used one, just seemed to be a good reason windows can't install without having at least one bootable HD at least, even if it is installed on a non-bootable drive.

    well flashed bios back to F9 from F11 (F10 wasnt listed).
    The RAID/XHD is now just RAID.
    tried doing RAID0 with 2 drives...still not bootable, and the 3rd drive showed up under boot order.
    tried all 3 w/ RAID0...still not bootable, nothing under boot order except 'add-in card'.
    next? :(

    Maybe it does not boot drives larger than 2TB?

    Is there a RAID1 option you can try with 2 drives?

    My guess this is the case though I can't see a good reason for it.

    I found this: The 2TB limit in Master Boot Record (MBR)
    Still does not explain why the RAID mark it unbootable.

    looks like MBR has a limit of 2TB...chike wins!...yah...I have an answer!
    now all I need to do is boot from a single drive...so next question:

    with the yel conns doing RAID5 where do I hook up my sata boot drive to get the best speed?

    thnks to everyone!

    chike...microsoft says booting from a partition over 2TB isnt supported, a limitation with MBR...u have to use GPT which isnt widely supported yet.

    Yes but you can make a smaller partition on the raid for the bood drive.

    EDIT: should be able to.
