bitlocker "unmountable boot volume" RRS feed

  • Question

  • trying to get bitlocker to encrypt our HD on a Dell inspiron 7520 has been a nightmare.

    Firstly, it said "This device can’t use a Trusted Platform Module" . The laptop has no TPM module.

    I followed this article to setup password/USB access:

    Now when I rebooted, bitlocker simply says it cant encrypt the HD becuase it is not unlocked automatically.  This is another incorrect error message as there is nothing locking the HD - there is no HD password or similar.

    Googling, it was advised to update BIOS, which I did (To A15)

    Then I enabled bitlocker for whole HD again, entered a password, saved the key to USB and also to windows account.

    Now when I reboot, and enter my windows login, it says "Unmountable Boot Volume"

    Does this mean my HD is now trashed, and everything is lost?
