Crossed out circle on start up
I'm having an issue with my Macbook Pro. When I start up my Mac, I see the Apple logo, but after 30 seconds the Apple logo changes to a crossed out circle.
Thought it was the SSD, but it works well when connected through USB.
When I put my old HDD at SATA cable, it works perfectly!
I thought the problem was the cable, but how it can work normally with the HDD?
Any help?
