i got a new ssd, and copied all files from my old hdd to the ssd. Now I have the ssd installed, but get a screen that says "no bootable device" that pops up. I have gone into the bios and tried to set the boot priority so the ssd is #1, but I still get the same response. The laptop only boots if I have both the old hdd and ssd installed. How do I make the ssd a boot device?
