I have a friends a1278 macbook and it had a bad drive (noisey/clunking/clicking etc). I got a Samsung 850evo ssd for replacement but can't get it running.
not sure what os it had
have no disks
ctrl option r
option...any sequence of any of these don't do anything for me. If I do nothing I get the ? Folder icon. Pushing option I get white screen only moving cursor (can't click on anything anywhere).
Put ssd in pc to verify drive was good. It was and I formatted it to hfs (using diskpart in dos). Now drive in mac will go to black screen saying no operating system. If I push option key it shows a hdd image with an arrow and says windows.
How can I load a dang OS!?
