Steps to Unlock Drive locked with BitLocker:
Click on start menu and type “BitLocker” in search box.
Select the “BitLocker Drive Encryption” from the search list.
Next to the drive that is locked, you will see Turn off Bit Locker option, click on the same and it will ask for permission for Decrypting that Drive.
Once you proceed with Decrypting it will take some time depending upon your Drive size.
