My setup: Windows 7 Ultimate x64 on ThinkPad T510. 1HD, two partitions (C and D). I just reinstalled my system and encrypted C; however, there is absolutely no option to encrypt D. I've tried accessing the drive from admin account and still nothing. When I open BitLocker management, it only lists partition C and not D. Here is some additional information that might or might not matter: I tried to restore my Windows 7 from an Acronis image and it was unsuccessful. Tried it twice and during booting POST showed two different W7s installed, which was incorrect. When I finally installed Windows 7 from scratch, the extra W7s were still appearing before startup and I had to use EasyBCD to remove them. Now when I am trying to backup partition C, Acronis says that my System Reserved Partition (SRP) is on partition D. My hunch is that Acronis messed up my drive D when I was trying to restore my C partition. Then when I did a fresh Windows 7 install, the SRP incorrectly ended up in D and since SRP cannot be encrypted, that means that my entire drive D can’t be encrypted either. Can that really be the case? If so, what is the quickest solution? I am dreading about going through formatting my 750GB HD and installing Windows 7 and encrypting it yet again. I read somewhere that you can use software like Acronis Disk Manager to move the SRP to drive C, but I am not sure how this will work because when I open the native winodws Disk Management, I don’t see SRP there. So I’m stuck and don’t want to format my HD if what I think is the problem is in fact not the problem.
