Installing Windows on SSD in optical drive bay I removed my HDD from the main bay to install Windows 10 (through BootCamp) on my SSD (in the optical drive bay) and then I put back my HDD.

After that, I can't boot Windows anymore. Is there a way to fix it other than putting my SSD in the main drive bay?

Thanks folks!
yes, there is a way to do this (I've got 2 drives and have been running this config for several years:  Mac OS on main drive, and FAT/winblows on optical bay)..

you have to first do the setup of the windows drive with it in the main bay (for some reason it won't recognize in the optical for purposes of BootCamp)...

Then after you've installed, you can move it over, then you can option-boot from it..
An added advantage of this setup is thatif you've got VMWare (fusion) you can also boot it as a virtualized OS from within Mac...
