    I installed windows 8 consumer preview with bitlocker enabled on drive 0, then I installed a hard drive with my previous windows 7 installation already on it as drive 1 (also bitlockered).  Using windows 8 and bcdedit, I added an entry to boot the windows 7 os.

    Everything works, but whenever I switch OSes, I have to enter the recovery key for that drive.  For example:

    Boot win8 -> enter recovery key for drive 0 -> reboot win8 -> works just fine until i reboot and select win7

    Boot win8 -> no request for recovery key -> reboot win7 -> request for recovery key for drive 1 -> reboot win7 -> works just fine until i reboot and select win7

    I've tried suspending protection and turning it back on in both OSes, but that doesn't seem to fix the problem.

    Other details:

    I encrypted the win7 partition under windows 8.

    When I boot win8, I have access to the win7 partition, but if I boot win7, the win8 partition shows up as locked even though they are both set to auto-unlock

    I don't have a pin for either drive

    Any suggestions?  I'd really rather not have to use the recovery key every time.

    Thanks!

      Hi,

      It is not recommend to encrypt Windows 7 partition under Windows 8. It may cause the issue.

        I am having the same issue of entering my recovery key every time I alternate OS. I am running windows 8 RC and Windows 7. My windows 7 partition was bitlocked in windows 7 only. Even suspending the bitlocker for windows 7 did not help and I have to enter 32 digit key every time. 

        I also have a 3rd drive for my data which was bitlocked using windows 7. If I try to access the data drive from Win8, it asks me for the recovery key. It asks me even after I lock and unlock my workstation. 

        Any suggestions?
