    Exclamation Crosshair V formula has problems with Windows 8 and RAID in UEFI mode

    Last weekend I had to reinstall my brand new Windows 8. As I had some problems with installation (basically installer could not setup MBR on my RAID) I came across UEFI option in my BIOS and decided to go for it.

    Exact configuration is as follows:
    Motherboard: ASUS Crosshair V Formula (BIOS from October 2012, the latest available for now)
    Drive:
    - 2x OCZ Vertex 3 60GB in RAID 0 mode, RAID set to UEFI DRIVER in BIOS
    - Western Digital MyBook 2TB (connected through USD 3.0)

    After fighting for nearly 6 hours I finally managed to install the system in UEFI. But, when extern drive is plugged during startup I immediately get a reset, i.e. POST goes fine, then for a fraction of a second I see blue Windows logo and then PC resets itself.

    I tried turning off external drive in boot priority list, but does not help. Each time problem is back.

    When I unplug external drive then everything works perfectly fine. I can plug in back when Windows starts and everything is simply more than ok. However, I don’t find this approach an acceptable solution.

    Any ideas how to fix that?

    all I can say is .. it is usb.
    (sounds like your raid loads before usb)

    there could be a solution .. among more knowing..
    but I think you found a workaround .. anyway.

    best of luck.keep us posted. ... Welcome to ROG.c.

    where did you get the "RAID set to UEFI DRIVER in BIOS"

    I have only IDE, AHCI and Raid in my bios. aside I don't get it, if you use EFI, you should have GPT not MBR ...do your self a favor, reset the bios, put your oCZ in raid mode , forget this UEFI that I don't know where you get it and re install windows without the external connected.

    Info you wanted:
    1) UEFI setup (where the option is).

    2) Setup that causes a problem. I think I tried nearly everything, i.e. changing order, disabling drives, etc. Nothing helps. When MyBook is plugged system freaks!

    Ok you means the ROM.... put it to legacy room and choose the raid to boot , not the EUFI , you will have to reinstall Windows , you will have of course to press CRT + I , ( not sure of the letter ) to configure the raid in the rom .

    I know this could work, but I'm looking for a way to stay with UEFI. Hopefully there is some.

    Have you tried going through the Hard Drive BBS properties? that is another area you can also force boot priority for drives

    Of course I tried this.

    So far neither disabling external drives nor changing boot priority (put Windows Boot Manager first) help :/
