Hi, tried booting my macbook pro mid 2011 model this afternoon.. to my suprise I recieved the question mark folder indicating my OS cant be found. The hard disk was replaced last year with a sandisk SSD and the RAM was upgraded. I have tried trouble shooting to narrow things down. - I was able to boot OS X from an external hard drive, however I am unable to see my hard drive - when I removed my hard drive and plugged it into another macbook externally I could see all of the files
Would this suggest issues with the sata cable? or something worse such as the logic board? any inuput is greatly appreciated, thanks
