Unlock BitLocker

Question

I have a problem with BitLocker. Previously I Turn on BitLocker and changed the OS. Now I can't unlock the BitLocker with the previous password. It shows the following message (figure below) when I ask for the recovery key. How can I solve this problem? Note that the partition that I locked with Bitlocker is a partition different from the partition that OS resides.

Hello AndualemGMedhin-5162,

Thank you for your question.

You can try using the Unlock-BitLocker cmdlet restores disk access with BitLocker.

To restore access, provide one of the following key protectors for the volume:

a) Active Directory Domain Services (AD DS) account
b) password
c) Recovery key
d) Recovery password

See the following example below on how to use it:

Example 1: Unlock a volume

$SecureString = ConvertTo-SecureString "fjuksAS1337" -AsPlainText -Force
Unlock-BitLocker -MountPoint "E:" -Password $SecureString

This example unlocks a specified BitLocker volume using a password.

The first command uses the ConvertTo-SecureString cmdlet to create a secure string that contains a password and saves it in the $SecureString variable. For more information about the ConvertTo-SecureString cmdlet, type Get-Help ConvertTo-SecureString.

The second command unlocks the specified BitLocker volume using the password saved in the $SecureString variable.
