But i lost it in the boot and cant boot MAC OS. (please see album with photos on http://imgur.com/a/N5zY2 )
I cant repair my system, when i click "check disk" on Fusion Drive it is nothing to do.
And if i want to re-install Yosemite, system did not see my Fusion Drive disks, only bootcamp (i have a windows too).
Any solution please?
