SafeBoot login screen is not appearing for the Sony VAIO with Vista Ultimate OS
I've created a install set using SafeBoot build 5400 and version 5.1.6. I've installed it in few machines. I've used the same install set in the Sony VAIO having Vista Ultimate. But after that when i restarted the machine i'm not getting the safeboot screen at all. It is struck with the starting safeboot screen. Please let me know how to bring back the machine to its original state and how to encrypt it using safeboot.
