Move a boot drive and get it to boot?

[pierre1610]

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?

no, windows is in bay 2. OSX is on a PCIE board on a 2.5" SSD in slot 2

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 .
