Boot up MBP from 2nd HDD installed in Optical Drive Bay
I have a Late 2011 MBP 13" and recently my Hard Drive stopped being recognized. So i took the cover off removed the drive installed it in an external enclosure and it worked. So i read here to install some tape above the SATA connector ribbon and i did but still didnt fix the problem. I also ordered the HD ribbon cable replacement and installed it and still no luck the laptop still doesnt recognize the HDD, i even tried ordering another cable hoping it was just a bad ribbon but still no luck.
So i bought a 2nd HDD optical drive enclosure and figured i dont use the optical drive ill just replace it with a hard drive and boot from there. I bought a new SSD HD, installed OSX El Capitan on it with my iMac using an external USB enclosure, installed the new SSD into the optical drive bay and connected/installed everything back on thr MBP and booted the laptop. When booted i get a flashing gray circle with a line through it, then it alters to the flashing question mark folder. I can press option while bootup and it recognizes the SSD but doesnt want to boot from it.
What am i doing wrong? Is it possible to bootup the OS from the optical drive bay with a SSD? The new SSD is a PNY CS1311 i also booted the SSD from an external USB enclosure and verified the drive/OS were both working.
Is this a good question?
