Windows 10: Correct Bitlocker password but failed to unlock drive

please help me! very frustrating. I used Bitlocker on my OS drive and two days ago, I was prompted to input password to unlock it when restarting Windows. However, after inputting the correct password I am 100% sure it is correct as retrieved from my Microsoft account, with matched key ID, it always showed "failed to unlock the disk". I tried everything I could find online, including the Command Prompt method, none worked. tried a few software and none worked either. Thanks!

HELP: Automatic BitLocker Unlock.

Please help,
Looking for a way( script or maybe some unknown windows command or registry hack) to automatically unlock a non OS BitLocker encrypted drive on Log-In.

My situation: Right now my OS SSD Samsung 840 Evo has a boot password, its not Bios option nor windows eDrive but the third one, the one you need 3rd party software to activate it, had to purchase EMBASSY Security Center to do it.
No issues here, the OS drive is locked and encrypted.

One of My HDD Drives is encrypted with Bitlocker, so every time my PC is booted, I need to enter windows log-in password and then open my computer and enter another password to unlock the drive.
Whats worse is that unlike the SSD that needs unlock password only after full shutdown the Bitlocker needs it every log-in.

Windows has an option to Automaticlly unlock all BitLocker drives on boot, BUT the issue here is that this official option only works if your OS drive is also BitLocker encrypted and then log-in password unlocks everything.

Im looking for maybe a windows Script or some Hidden command to automatically unlock the BitLocker drive.

Even if it Sounds insecure like having the actual password somewhere in the registry, text file or script I dont care because the OS drive is encrypted and passworded.
Also I have a TPM chip I can encrypt any file/folder so even if file is copied from my PC when its fully unlocked the files wont be readable anywhere unless unencrypted before.

If its important im on 8.1 pro 64bit

P.S. If there is no solution for my problem then my only choice is when windows 10 comes out to do a clean install on another Samsung 840 Evo that was previously cleared and eDrive option enabled


Thanks in advance.

Bitlocker password 256 characters breaks unlocking


I'm not sure I fully understand, as the link you provided already contains the answer?

So, even if you used 256 characters for the main password, is there a reason you can't use the 48 character Bitlocker recovery key (which is different to the main password) to recover the drive?

You can find a tutorial regarding using the Bitlocker recover key to unlock a drive at the following link:
