Windows 10: Can I auto unlock my D: drive when booting up my laptop without havin to type in the...

I recently changed my small SSD C: to a larger SSD in my Dell 17 laptop. Unfortunately when cloning the drive using Macrium I did not turn off Bitlocker and now I have to type in the Bitlocker key to unlock my other drive with my data on each time I switch it on. How can I set it to unlock automatically when booting up the laptop?

Turning on Bitlocker's auto-unlock on partitioned drive

I have Windows 10 Pro running on a 500GB hard drive which is partitioned into C: for Windows programs and D: where I keep my documents. I want to secure my documents and personal files from unauthorized access.

Anyone with a Linux bootable USB stick can boot a computer from the USB stick and then access all files on the hard drive. To prevent this I have used Bitlocker to encrypt my D: drive. The drive now cannot be accessed if laptop is booted externally.

I now want to turn on "auto-unlock", so that when I boot into Windows through the laptops' Window OS the D: drive is automatically unlocked. When I select "turn on auto-unlock" on the Bitlocker Drive Encryption screen I get the error message "The operating
system drive is not protected by Bitlocker Drive Encryption."

Why will it not allow me auto unlock the drive?

 

Cannot set auto drive unlock by Bitlocker upon boot

Hi,

I don't know what I (or Microsoft) did wrong this time, but on one PC I cannot setup Bitlocker to auto-unlock drive D:\ upon boot. I have other PCs also set with Bitlocker, but all unlock automatically, only this one does not want to.

UNLOCKING only offers options to:

- enter password

- More/Less options (bold text)

- Enter recovery key

- "auto unlock" option is missing





When I click on "Turn on auto unlocking", message pops-up.

But D: is NOT operating system drive. C: is OS drive!





Auto-unlock should work for non-OS disk, as per Microsoft:





But when I click on ADVANCED OPTION upon unlocking, there's no option to "Auto unlock" (you will see, it's in Slovenian language, but obviously 1 option is missing).

Also when I try to manage AUTO UNLOCK from Bitlocker SETTINGS, when I click on "Auto unlock" link for drive D:, warning pops-up saying that System drive C: is not setup with Bitlocker. I know, I do not need C: to be encrypted, as all data is on D: drive.

System is healthy, Win10 with latest patch. SFC /SCANNOW does not find any errors.

TPN is in "Ready to use" state, but I think there's some difference between Password and TPM locking. Might that be an issue?

Ideas?
