    I have OSX installed on a 2.5" SSD on PCIE board. I want to move it to a main SATA II slot for a month or so to make use of a borrowed SSD blade for scratch space.

    When i move the drive it obviously can't find OSX and i get a question mark folder at boot. CMD-R doesn't work as it can't see the drive in bay 1 SATAII slot. How can i remap my installations? I really don't want to reinstall the OS as i have bootcamp too which would mean reainstalling 2 OS's.

    Thanks

    Both Windows and MacOS on the same SSD?

    If you are not using Nvidia Maxwell / Pascal GPU, then try PRAM reset.

    And if you hold "alt"-key at start up. Do you see the OSX drive when it is in bay1? I have done the same thing with SONNET PCIe SSD card. And it worked. I just moved the SSD to bay 1, or you could try the SATA cable from the CD player 2. Then it will be called disk0.

    Should work without trouble .
    As said above, you could try the Alt key at boot; if our system drive doesn't show up, it might not be connected / installed properly .
