After SSD upgrade Flashing folder with Question mark during startup
Hi,
I have a very interesting problem with my Macbook Pro 13" early 2011.
My hard disk is functioning, but working slow. That's why I want to upgrade to a SSD.
The new SSD is working very well (testing) on a Macbook Pro 13" early 2011 from a friend and one Macbook Pro 15" 2014, but does not function on mine.
When I replace the harddisk with the SSD I get the "Flashing folder with Question mark" .
I replaced the internal harddisk cable, but with no result.
I also did a PRAM reset.
The SSD drive does get recognized by Apple disk utility for formatting etc....
Don't know where to look anymore.
