    I recently installed a new SSD in the HD bay and moved the HDD to the optical drive bay with a data doubler. After doing so, I tried powering on NY Mac and it does indeed turn on. You can hear the fans turn on and the power in button turn on, but the screen is black! Nothing shows up!

    I have a Mac Book Pro mid 2012
