Windows 10: "the operating system drive is not protected by bitlocker drive encryption"

Hi.

My pc has 8 drives attached to it.


A: sata ssd

B: usb

C: m2 nvme

E: m2 nvme

U: sata ssd

W: usb

X: sata hdd

Y: sata hdd

E, U X and Y are bitlocked.


I wanted to turn on the auto-unlock feature, which worked fine except for drive E, which give the error,


"the operating system drive is not protected by bitlocker drive encryption"


E isn't the os drive, but it is a fixed data drive, whereas the others are categorised as "removable".

I'm not sure what that means or how I ended up configured this way.

Can anyone explain this? How do I turn on auto unlock for E: do I have to encrypt C: as well?

How have I ended up with the sata drives being catagorised as removable and the nvme fixed? Is that a consequence of the connection type? Or did I stuff something up when built the machine?

Thanks in advance

:)

 

Bitlocker Drive Encryption

Recently I was attempting to encrypt my drive with bitlocker because windows was suggesting to encrypt them via the security page when logging into my account. Though, when I do attempt to encrypt them with bitlocker it states that my drive is already
encrypted via bitlocker. I was wondering if there was a different way that it needs to be set up because I was hoping to add the extra layer of security to my drives with bitlocker encryption and password protecting them via a recovery key.

 

Need to turn off Bitlocker to install Windows 10

Hi,

We suggest doing the following steps again to resolve the issue. To complete the procedure, make sure that you have the following information:

• You must be able to provide administrative credentials.
• The drive must be BitLocker-protected.

To suspend BitLocker Drive Encryption on an operating system drive, please follow the steps below:

• Click Start, click Control Panel, click
  System and Security, and then click BitLocker Drive Encryption.
• Click Suspend Protection for the operating system drive.
• A message is displayed, informing you that your data will not be protected while BitLocker is suspended and asking if you want to suspend BitLocker Drive Encryption.
  
• Click Yes to continue and suspend BitLocker on the drive.

Let us know how it goes.
