Hello, I have taken my old Filevault 2-enabled boot disk (Lion 10.7.4) and put it n a new MBP 2012 to act as a boot drive. Plan being just to keep the installation. When starting after having selected the CS volume as bootdevice, there is no login screen to enter the known password. On the ld MBP, it always appeared. Consequenty, booting fails with a hit screen, and a crossed-out crcle. I can mount the CS volume fine from the hard dsk utility. Cn you advise on what t d n order to get the login screen back? Thanks.
