Hello I have encrypted the hard disk of my Lenovo W700 with Bitlocker (TPM + PIN and 256bit AES with diffuser). I use Vista Ultimate 64 Bit and have installed all updates. The problem is that every time I start my computer I have to input the bitlocker key (not only the pin but the whole recovery key)! I have deactivated and activated Bitlocker several times. This is what Microsoft suggests to do. So that all new system configurations are applied and they are registered with Bitlocker. But that doesnt help. Even if I do not change anything on the system I have to input the key after a restart. What should I do now? Can anyone help me, please? Thanks Enrico
