    1) I am currently booting OS-X via SSD on Apricorn x2 on PCIe #2.

    2) I have no other HDDs/SSDs on any of the internal bays.

    3) I have a second SSD on another Apricorn x2 on PCIe #3.

    Why is that when I load bootcamp up and click "Continue", nothing happens? My guess is that bootcamp sees both SSDs as external drives, so no game. If that's the case, how do I tell OS-X those are internal drives?

    you need to have a disk in bay one. Bootcamp will only install to that disk too.

    Hi Nox.

    I've been struggling to get an Apricorn Velocity Solo X2 to dual boot OS X / Windows on a single SSD in a Mac Pro 5,1, and you seem to be the only person to have got this to work. If you could give me some pointers I would be grateful.

    1. Did you get it working with Windows 7 as well, or just Windows 8?

    I've tried both, installing Bootcamp with the SSD mounted in a bay first (bay 1 for W7; the lower optical bay when I did W8), modifying for AHCI support, booting Windows with the empty X2 in a PCIe slot, then moving the SSD to the X2. OS X (Yosemite) always works fine, but I get a black screen with "no bootable disks found" (or similar) when loading Windows.

    2. Is there a particular thing you did that I didn't?

    3. Is there a BIOS screen on the X2 that can be accessed?

    4. Is there an issue relating to attached drives being seen as external? If so, can rEFInd or similar overcome this?

    5. I noticed from your other posts that you eventually went back to just using a regular drive bay, describing occasional lockups in Windows. Would you advise against even bothering, then?

    I realise the speed difference is probably minor in practice, and boot is delayed a little, but would like to try it before returning the card.

    Many thanks.
