Hey guys, doing the upgrade on my 840 Samsung SSD in mid 2012 cmbp. Made the DVD with the newest firmware, it popped up on the startup disk, I picked it and restarted...
Now it says...No bootable device... Insert and press any key... Of course nothing works when I press it... If I turn off and on it goes to same screen.. I'm stuck at the black screen...
Where'd I go wrong??
