    Hello All,

           I have machines that I am deploying Win 7. I want to encrypt the OS volume using bit locker. As part of future upgrades I want to boot to a usb stick in the Winpe environment. I then would like to unlock the OS drive (while still in Winpe) and do the upgrade.  Also I just want to use the tpm password and not have to save a security key to a file. Can anyone tell me if this is possible?

    Hi,

     

    Based on my research, I suggest you try the following steps to unlock an encrypted volume.

     

    Type the following command at a command prompt, and then press ENTER:

     

    cscript %systemroot%\system32\manage-bde.wsf –unlock Volume : -rk PathToExternalKeyFile: \ External Key File Name

     

    For example, if you want to unlock volume D and if you have stored the Recovery Key on the drive J, type the following command at the command prompt, and then press ENTER:

     

    cscript %systemroot%\system32\manage-bde.wsf –unlock D: -rk J:\ External Key File Name

     

    Note The external key file name is listed in the script output.

     

    If the Recovery Key is damaged or missing, you can still unlock the volume. To do this, type the following command at the command prompt:

     

    cscript %systemroot%\system32\manage-bde.wsf –unlock Volume : -rp Numeric Recovery Password

     

    Note The numeric Recovery Password is listed in the script output.

     

    For more information, please refer to the following article:

    Hope this helps.
