I found it - You have to enter 2 commands from a comand prompt to repopulate the TPM chip on the new laptop witht he recovery key. Manage-bde protectors delete C: -type TPM Manage-bde protectors add C: -tpm That done the trick. Thanks - Joe.

I moved my hard disk to another laptop which had bitlocker configured. when it boots up it prompts me to enter key (expected). I enter key and log in. I run TPM.msc and select clear TPM. I then have to reboot, F1 to accept clear TPM - enter recovery key again. Log in win7, Prompted to reboot to Enable TPM, reboot, accept TPM enabled prompt, Enter recovery key again then log in to Win7. I thought that would be the process but every time I reboot it promtps me for the key again... Any idea what i'm doing wrong? Thanks Joe. Thanks - Joe.

Hello! Why dont you try connect the hard drive where it was originally when you activated the Bitlocker and once youve disabled it there you try again to connect it to your laptop? Maybe it could works :) Good luck! Manu.Si esta respuesta le ayud a solucionar su problema puede marcarla. Esto ayudar a otros usuarios a resolver su mismo problema. Participante en news.lechado.com

I would add... "A Trusted Platform Module (TPM) is a microchip that is built into a computer. It is used to store cryptographic information, such as encryption keys. Information stored on the TPM can be more secure from external software attacks and physical theft." So the TPM is in the original machine where you activated Bitlocker, so I think that maybe for this reason it is asking you the key and you can disable it... ;-)Si esta respuesta le ayud a solucionar su problema puede marcarla.
