This procedure is for recovering data from a disk drive with Microsoft Bitlocker Full Disk Encryption when the drive no longer boots.

Also, a lab for practicing this procedure will be provided here: https://gameofpwnz.com/dislockerlab/

Required tools

The computer and hard drive that has Bitlocker
USB Drive: Needs enough storage for files that need to be backed up
Kali Linux Live USB or CD/DVD (Kali Doc, Null-Byte Doc, Wireless Shack Doc – CD/DVD)
Bitlocker Recovery Key or Bitlocker Password (Active Directory Bitlocker Recovery – only if saved in AD & Microsoft TechNet Doc)

Procedures

Make sure the hard drive with Bitlocker is connected. If you never removed it, then you’re good.
Boot from Kali Linux Live USB or CD/DVD.
Update:
apt-get update
Install git and dependencies:
apt-get install git libfuse-dev libmbedtls-dev cmake

5. Git clone Dislocker:

git clone git://github.com/Aorimn/dislocker.git

6. Change working directory to the dislocker directory

cd dislocker

7. cmake the Dislocker directory

cmake .

8. Make and make install

make
make install

9.Find the drive with Bitlocker

fdisk -l (should look like /dev/sda# if SATA/SCSI)

10. Create directories tmp and dis

mkdir /mnt/tmp
mkdir /mnt/dis

11. Run Dislocker

Using Recovery Key: dislocker -v -V /dev/(whichever is the one you found in Step 9) -p<Bitlocker Recovery Key> — /mnt/tmp
1. Hopefully you saved your recovery key in Active Directory or somewhere you know. The Recovery key is 55 characters with the hyphens.
Using Bitlocker Password: dislocker -v -V /dev/(whichever is the one you found in Step 9) -u<Bitlocker Password > — /mnt/tmp

12. Check if it worked

ls /mnt/tmp (You should see a dislocker-file. If so, then it worked)

13. Mount the volume

mount -o loop,ro /mnt/tmp/dislocker-file /mnt/dis

14. Change working directory to the volume

cd /mnt/dis

15. List out directory listing

16. Backup files

To make this easier, open up the GUI file explorer window (2x). In one, open the USB drive. In the 2^nd, open up /mnt/dis. Then copy the files that you need to the USB.

17. Profit
