  1. Hi, I brought a new HDD for my Macbook Pro . and connected to the system . it started showing me a flashing folder with question mark error. Then I figured out that the HDD is not being detected. I Connected it to a windows machine and converted it to GPT format and set the partition active in the command prompt. Again I connected it to my laptop and now HDD was detected. but it says "MISSING OPERATING SYSTEM" I tried all the combination keys like Cmd+R, Cmd+Option+R etc but nothing works. I am able to get the drive option when I press option at the start and when I select it, again the same msg in the black screen "MISSING OPERATING SYSTEM" I am not able to get the Internet recovery or the Globe for internet download. Old HDD has been formatted and no files .. :-(
