I have a laptop running windows 7 ultimate. I have encrypted my drives using bitlocker. Now I have also installed lubuntu along with windows. But my encrypted drives are not visible in linux. Hence I need urgent help?

I do not believe that Linux has the ability to view the contents of a drive encrypted by bitlocker. Bitlocker is a Microsoft version of say TrueCrypt, its not designed to be compatible with other operating systems, it requires an add-on to even work on Windows. –  Ramhound Jan 9 '12 at 19:14

You can access BitLocker partition under Linux using Dislocker, an opensource driver which is using FUSE (or not).

For that, you need the file on a USB key (the one with the .bek extension) or the recovery password.

Fairly recent file dates, looks like it's being maintained. With write capabilities. –  Fiasco Labs Oct 21 '13 at 23:04
    
It seems @Aorimn is mantaining a version on github: github.com/Aorimn/dislocker/tree/develop –  adosaiguas May 21 at 0:29

Thanks to Aorimn, his solution worked for me. I'm fairly unexperienced with Unix, so it cost a few hours to figure it out. I thought I would describe the steps I took while my backup is running :)

My problem was that I could not boot Windows, and I needed a way to access my files on a Bitlocked partition. In order to do this, you need a bitlocker recovery password (8 groups of digits) and the ability to boot your system from USB.

  1. Download and install LiLi on an other Windows machine (Linux Live USB Creator)
  2. Start LiLi and have it download a lightweight ubuntu image. I chose Xubuntu.
  3. Install the image to your USB stick.
  4. Boot the problematic machine with the USB stick
  5. When you see the ubuntu boot screen, press a key.
  6. Under F6, set the following options: nomodeset, acpi=off, noacpi and nolacpi
  7. Boot ubuntu.
  8. Make a folder /media/windows and /media/mount.
  9. Download and extract dislocker
  10. sudo apt-get install libfuse-dev
  11. change directory to the dislocker/src folder
  12. sudo make
  13. sudo make install
  14. change directory to /usr/bin
  15. sudo fdisk -l
  16. identify the partition which is bitlocked. Mine was /dev/sda1.
  17. sudo dislocker -r -V /dev/sda1 -p315442-000000-000000-000000-000000-000000-000000-000000 -- /media/windows (replace your own bitlocker key and source partition)
  18. change dir to /media/windows (use sudo -i if you can't access it)
  19. mount -o loop dislocker-file /media/mount
  20. You should now see your files in a mounted drive of the file manager.

Backups are fairly slow, but it might save some trouble if you do end up reinstalling windows. Good luck!

From the above steps I wasn't clear how dislocker is functioning, so here is the info, from the source "With FUSE, you have to give the program a mount point. Once keys are decrypted, a file named dislocker-file appears into this provided mount point. This file is a virtual NTFS partition, so you can mount it as any NTFS partition and then read from it or write to it." –  xpt Feb 20 at 14:59

The only thing I've found that might help you is this. It's an experimental fuse driver that allows you to access BitLocker volumes. It's still in an alpha state, and it looks like you'll have to compile the code yourself. It also only allows read-only access, and some things might not work. I think it's your best bet, though.

I agree this is probably your best bet at the current time. –  Mark S. May 19 '12 at 2:48
    
for those that downloaded extracted and installed dislocker, and find it to be a bit buggy, use this command while cd'd in the src folder. sudo make uninstall –  blade19899 Oct 12 '12 at 16:58
    
@MichaelHampton NVbit: Accessing Bitlocker volumes from linux. Looks good to me. –  SaintWacko Jan 7 '13 at 14:25
    
How usable is it? Apart from "The code is in alpha state."", I also see "The research was done around an year ago.Work was stopped prematurely,Don't expect things in clean/finished shape." Moreover, It also only allows read-only access, while dislocker at least allows RW access. Any first-hand experience-user comment please? –  xpt Feb 20 at 15:05
    
@xpt I don't have any experience with it, I just found it through Goole-Fu. I would recommend using Dislocker, as it's newer, and appears to be in much better state than what I found. –  SaintWacko Feb 20 at 16:38

Bitlocker is a proprietary, closed-source drive encryption system only supported by Windows. You'll have to remove Bitlocker encryption if you want to access your Windows partitions from Linux.

See What is the difference between disabling BitLocker Drive Encryption and decrypting the volume? for instructions on doing so. It would be advisable to have a backup of your data completed first.

Once the drive is decrypted, you can use TrueCrypt instead; reading a System Encryption volume under linux isn't supported by default, but someone has figured out a work-around. See How to use TrueCrypt®-encrypted Windows system drives on Linux

At the very least, review the TrueCrypt documentation and more specifically, the list of supported OSes.

Yet another option is PGP Whole Disk Encryption. See PGP Whole Disk Encryption for Dual Boot Linux and Windows XP
