    Hi!

    I just bought a Samsung 850 EVO SSD and I wanted to install it in my MacBook Pro 15' late 2011. Since I did not have a SATA usb cable, I used a case in order to format it and create a GUID table partition.

    After that, I physically installed the ssd into my MBP but when booting, and after pressing the option key, it does not appear in the detected devices. The only device that appears is the usb with the Yosemite OSX installer that I was planning to install into the ssd.



    Does anybody know why this could be happening or how to solve it? I don't know if it could be the SATA cable but it has always worked fine with my HDD.



    Thank you

    You need to install the OS on the SSD before it will show as a bootable device when using the option key at start up.

    So, I recently installed a 850EVO in my Early 2011 MBP. I did a time machine backup before the swap, swapped it, then booted into the net recovery mode (Command + R). From there I formatted the 850 using Disk Utility then did a restore from time machine backup. After it was done doing the restore and I could boot into the OS again, I went back to the Net Recovery mode and did a permission repair twice to make sure everything was good. and that's was it.

    As mentioned above it was nothing going to show the Disk as that screen only shows you bootable drives to select. Sometimes it will even show that Net Recovery mode but other times you need to use the boot key command. This is normal.

    I have the same setup! Like the others said, you have to install the OS first before it shows up on the boot selection screen. It's a nice device.

    Thanks to all! I installed the OS in the ssd before installing it in my MBP and it worked perfectly.
