Issues booting mac from ssd
I hope you still ready this - it has been a while.

I spent my whole Chrismas and new year holidays fighting with similar situation.

I found out the main issues are:


MBR vs GPT (please google)
disk letter ID (e.g. C: - D: ....)
use some third party software to deal with partition and disk address
use some third party software to Clone the disk.


Good luck !
