Use (Windows) BitLocker-encrypted drive on Ubuntu 14.04 LTS

Since Ubuntu 18.04, Dislocker is available in the Ubuntu Universe packages. It can be installed using

sudo apt install dislocker

You may need to

sudo add-apt-repository universe
sudo apt update

---

First, we make two folders, /media/bitlocker and /media/mount:

sudo mkdir /media/bitlocker /media/mount

Then, download and then extract Dislocker.

You'll want to install some needed packages:

sudo apt-get install libfuse-dev

To install it, we need to change directory to the dislocker folder:

cd dislocker

Depending on your operating system, you'll need to choose one of these:

• For Debian-like distos based on Debian Jessie or Ubuntu 14.04 or older:

   aptitude install gcc cmake make libfuse-dev libpolarssl-dev ruby-dev
  

• For Debian-like distos based on Debian Stretch or Ubuntu 16.04 or later:

   aptitude install gcc cmake make libfuse-dev libmbedtls-dev ruby-dev
  

Now we finally install dislocker:

cmake .
make
sudo make install

Here, we need to find our partition so we dont erase all of our drives accidentally:

sudo fdisk -l

If we have a recovery password, we can decrypt it using this:

sudo dislocker -r -V /dev/sdaX -p1536987-000000-000000-000000-000000-000000-000000-000000 -- /media/bitlocker

PS: You should replace 1536987-000000-000000-000000-000000-000000-000000-000000 with your recovery password.

If you know your password, we can just use that too:

sudo dislocker -r -V /dev/sdaX -uPASSWORD -- /media/bitlocker

Pssst: Replace PASSWORD with your User password. Attention: keep the u before the password! So, if your password is UbuntuLover, you shall use uUbuntuLover after the hyphen.

If your disk is mounted to sdb, use option sdb1.

If you are decrypting with a recovery file then use "path/to/.BEK" instead:

sudo dislocker-fuse -V /dev/sdcX -f /media/user/usb-drive/00000000-0X0X-0XX0-XXX0-XXXX0XXX00XX.BEK -- /media/bitlocker

Now, we finally mount our file:

sudo -i
cd /media/bitlocker
mount -r -o loop dislocker-file /media/mount

(If the mount above fails with "Permission denied" add the -r option and try again.)

Now you can move to the /media/mount folder and see your decrypted data.

Read the source for more information and details.

You need Dislocker to use BitLocker-encrypted drives. You can download it from here or there is a GitHub repository also.

To install it you will need:

• A compiler, GCC or Clang;
• Make (or gmake, for FreeBSD)
• Headers for FUSE;
• Headers for PolarSSL;
• A partition encrypted with BitLocker, from Windows Vista, 7 or 8.

For detailed instructions, see this page or refer to install.txt file in the downloaded Dislocker archive.

Very good tutorial, however there's one problem. Since the file is read only you will need to use the read-only flag:

mount -ro loop dislocker-file /media/mount

Also the -u (--user-password) option to make this much easier:

sudo dislocker -r -V /dev/sdaX -u -- /media/mount
Enter the user password:▯ 

If you want to mount again in the same folder use:

sudo dislocker -r -V /dev/sdaX -u -- -o nonempty /media/mount

(Where X should be replaced by the number of your encrypted drive, e.g. /dev/sda7)
