== I believe there is a size limit of 128 GB on the boot drive. == '''If the drive has NOT been formatted using OS 10.2 or latter. '' Repartition the drive so your boot sector is less than 128 GB.'' ''' ''Clone/dupe to that sector and see if it will recognize/boot.'' '''Other solution would be to format and install OS X.x on the new drive''' ''then use Migration Assistant to transfer your files.'' Good Luck, N.
