Windows 10: Bitlocker Process - 2 bek (startup) keys and one recovery key Solved

    Bitlocker Process - 2 bek (startup) keys and one recovery key

    I don't know if this what should happen but I was watching the process of key storage as I went through the BitLocker encryption process.

    To see what was happening on the usb drive to which I was saving the startup and recovery keys I had to enable 'show system files' in order to see the .bek key.* I have seen posts stating that these are 'hidden files'. Maybe they are both? I am assuming that if the restart to check that usb key works succeeds, then presumably the machine is 'booting' from the usb key (.bek file)...?

    1. Turned bitlocker on the C drive
    2. usb drive was preselected to save STARTUP KEY
    3. clicked on save
    4. ONE bek key created on USB drive
    5. Question re save location for recovery key > selected save to usb flash drive
    6. USB drive preselected > clicked on save
    7. Another bek key and recovery key saved with same timestamp
    8. clicked on next > encrypt entire drive > run check > restart

    So TWO .bek (startup) keys......Does anyone know why two?

    One for each partition although I did not yet have BitLocker turned on my data partition.
    Or maybe one for the Windows recovery partition?* Although I thought I had read that this remained unencrypted...?

    answer to two bek keys

    Just worked out what it is. There is a bek key for StartUp and a bek key for Recovery. A bit confusing as there is also a 'BitLocker Recovery Key' (different format to bek Recovery key)....???

    Can anyone shed any further light?

    Must be that the system partition requires both startup and recovery .bek keys.

    The data partition appears to only have one .bek key, presumably a recovery key.

    The encryption of both system and data partitions has created just one BitLocker Recovery Key in a text file for each partition.
