Windows Vista To Make Dual-Boot A Challenge? 442

Posted by Zonk from the have-to-raise-a-fuss dept.
mustafap writes "UK tech site The Register is reporting on security guru Bruce Schneier's observation that the disk encryption system to be shipped with Vista, BitLocker, will make dual booting other OSs difficult - you will no longer be able to share data between the two." From the article: "This encryption technology also has the effect of frustrating the exchange of data needed in a dual boot system. 'You could look at BitLocker as anti-Linux because it frustrates dual boot,' Schneier told El Reg. Schneier said Vista will bring forward security improvements, but cautioned that technical advances are less important than improvements in how technology is presented to users."

      One slight detail.

      Drive encryption is optional. It's something you may configure while setting up the system for systems carrying sensitive or important data. It's not like a standard Vista install automatically encrypts the entire drive. That would be ludicrous.

      Bruce Schneier may be a brilliant security guy, but like every other person (and company) on the planet, he has an agenda. Don't automatically trust the guy telling you stuff because it's embarassing to the person he's telling you about.

        Does it really matter? If you're going to format a drive as FAT32, it's already in your best interest to use Linux's version of fdisk rather than Windows XP's. Window's current fdisk limits FAT32 partitions to 32GB; this is entirely a software limitation, FAT32 allows for volumes up to 2TB. So unless Vista does something that prevents mounting a non-Windows formatted FAT32 drive, we should be fine.

      Bitlocker is a whole-volume, hardware based encryption system (as opposed to file-specific techologies, such as Encrypted File System, which have overhead that requires a specific filesystem like NTFS. There is no filesystem specific overhead because it's transparent to the filesystem, and to the applications for that matter) -- there is no reason I am aware of for it to be tied to any specific filesystem, and it should encrypt FAT32 just as capably as NTFS.

      Not only is this functionality optional, and requiring special hardware support, but it is a bonafide feature. The data of the world would be much safer if every laptop swiped, hard drive sold on ebay, and incident of unwanted physical access of machines couldn't give absolute access to every file on the machine.
    • Right now, I'm using Win98SE and Linux. I just upgraded from RedHat 9 to FC 5. Under either version, I can mount my Windows drive, but no matter what arguments I give mount, it's still read only. So far, I haven't been able to find the magic incantation to allow write access to my FAT32 partition from Linux. Yes, I can put the files on my flash drive if they'll fit, but I shouldn't have to.

        i don't know if this is a troll or an actual problem, but how about you try -t vfat -o rw [die.net]?

    • Windows obviously doesn't store the private key on the hard drive, because otherwise there's no point in encrypting it. But you could certainly give another operating system enough information to recreate the primary key and transparently decrypting it.
    • Exactly, this is a non-story. NTFS support in linux is not safe as far as I'm aware. All of the NTFS mounting tools I've tried have recommended mounting read-only unless you really have to.

      And the other way? If you know of a Windows ext3 or Raiser driver, then please tell me. Basically, nothing has changed.

      FAT32 is the only common ground both OS's have, and that sucks. It handles ungraceful shutdowns badly (chdsk001.dat anyone?) and has no ownership / execute flags whatsoever. As others have suggested,

    • Okay, first off, the article headline is HORRIBLY misleading. BitLocker will NOT ENCRYPT THE ENTIRE DRIVE. It is required that you have a ~100MB partition in order to boot off of, which will then in turn load the needed software into RAM and *then and only then* decrypt the encrypted partition.

      Read: This has nothing at all to do with dual booting. Your ability to dual boot will remain completly unchanged, period. This, however, is about your ability to share data between OSs, not your ability to boot two. Learn to write a article headline, please.

      FAT32 is dead. Period, get over it, dead. No, I take that back, it still has one use: flash drives, and other forms of removable media. Other than that, IT IS DEAD. Why? Simple: security. From Windows 2000 and on, Microsoft actually put some degree of effort into security. "Some degree?" you ask? End result, due to NTFS, you can actually secure your system. Compared to FAT32 anyways, where a *guest* user can drop a virus as c:\explorer.exe, and then the next time Johnny Admin logs in, it's over. NTFS added actual security measures. ACLs. Execute bit. And, well, quite a bit more. Due to this, I can say the following without doubt that I'm right:

      1) BitLocker will ONLY work with NTFS.
      2) Vista will do everything they can short of threatening to eat your children to get you to install on NTFS. (Side note: http://www.theinquirer.net/?article=30128 [theinquirer.net] vs. http://www.microsoft.com/technet/windowsvista/libr ary/plan/5025760b-0433-4ba1-a2f4-9338915fdb4b.mspx [microsoft.com] - Beta1 won't install on FAT32, but according to offical MS docs, it will (eventually, most likely))
      3) If you're still using FAT32 as your primary OS partition, you're an idiot.
      4) Due to #4, if your defense is, "my [windows] OS can't run on NTFS!", my response is still the same. Go upgrade, you're not helping anyone.

      FAT32 is nice for removable media. That's about it.

      (</troll>)
    • Any body that is dual booting will also know that making a partition formatted fat32 will allow copying of files between os's.

      Or, maybe we could actually put on a thinking cap and just not turn on BitLocker? Wow, what a concept...

      Does anyone get this? It is NOT TURNED ON UNLESS YOU TURN IT ON?

      So if you are Dual Booting, simply don't turn on BitLocker, because you would have NO reason to. Makes perfect sense to me, and I don't see any motive in this technology, and yes I have used it on test systems.

      Shocking.

      Will it be possible to mount non-encrypted disks in Vista? Well, unless MS is finally prepared to kick backwards compatibilty then yes.

      Even if unencrypted HD's ain't supported (unlikely) they would still need to support regular filesystems like FAT for all those flash disks from your camera and USB keys and such.

      I am as anti-ms as you can get (if I am ever diagnosed with an incurable disease Gates gets a bullet in the head the next day thanks to my Halo training.

          • ext2ifs [fs-driver.org] NON-opensource (maybe violating GPL ?) native read/write support for ext2 (and ext3, but the driver could fuck-up the journaling if partition wasn't unmounted clean in linux). Has a nice GUI to assign drive letters to partitions.
          • rfstools [p-nand-q.com] and GUI Yareg [akucom.de] application that reads files from an reiserfs partition.
          • rfsd [sourceforge.net] - native reading support for reiserfs


          This shows that :
          • It is possible to add access to linux partition in windows
          • Even write access is possible and currently the non-open source ext2ifs [fs-driver.org] provides a solution that can be read/written by both OS and which is a little better than FAT32
          • although Windows has no propper device mapper but only Dynamic Drives, LVM2 data can still be accessed (although not with a native driver).
          • None of this numerous attempt is done by Microsoft. This show how much they want to play nice with the others

    The only reason I was considering Vista is because Microsoft have made sure DirectX10 won't run on XP.

    Now if I also can't dual-boot then that's the last straw to drive me to a linux-only system.

    And before anyone suggests it, no I don't want to be running Linux under a Microsoft VM.
  • Couldn't this be worked around with virtualization? I.e. run both Vista and a free OS on the same box, communicate over TCP/IP. Kludgy, yes, but better than nothing I guess.

    Ok... I've been a linux fan for 10 years or so now. Haven't run anything but linux in about 7 years. But c'mon guys this is FUD.

    First of all, vista won't have this activated by default. Here's how you can turn it on in Vista Beta:

    And yes it will make any data encrypted in this manner unavailable to another operating system. It does this by using TPM (Trusted Platform Module) in the BIOS and can base the key on the kernel and optionally: just the bios, a user supplied key, or a USB drive supplied key.

    This allows for the option of encrypting/decrypting data from the very start of the boot process. And guess what? It's being implemented in linux too!

    http://lwn.net/Articles/144681/ [lwn.net]

    BitLocker from windows is just a kernel based drive encryption software that takes advantage of TPMs just like the linux system. If you're concerned about cross platform compatibility then use user space encryption rather than kernel space encryptiong. If you're that concerned about secure keys then don't dual boot! If you love dual booting and don't care about encryption at all, noone is going to beat you up and make you use encryptiong.

    • Yeah, this is just stupid. OS X has the capability to encrypt the user's home folder, but that doesn't make it any more "anti-linux" than this makes Vista.
    • I might take off the tinfoil hat, but I'd consider keeping it handy depending on how open Microsoft is about it's encryption methods.

      Will it be possible to write a driver for these encrypted file systems without having to reverse engineer the encryption? Or will Microsoft tell people their encryption algorithms so that competitors can write drivers? Or is Microsoft using some standard algorithm (DES, RSA, or whatever)?

      If Microsoft does the, "Oh, sorry, we won't tell you how to decrypt the data because you

  • From TFA: Vista is due to feature hardware-based encryption, called BitLocker Drive Encryption...

    The hardware part worries me. Is it just that the hardware is used to speed up the encrypt/decrypt stage? Or is it that disc encryption is actually tied to a specific unique chip on the system?

    A company plans to include a very useful encryption tool with it's next OS.

    This is good news in terms of security and privacy, and therefore /. readers will welcome it.

    Oh wait, no they won't, because the company is Microsoft. Microsoft is baaad, therefore everything they do is sinister and evil. You people always manage to find the dark lining to their every silver cloud.

  • The only thing I still dual-boot for is games, and that doesn't require accessing the Windows partitions from Linux.
  • But honestly in the day and age of cheap computing why even bother dual booting? I think I'm probably your average slashdotter, I have a laptop running windows XP, a desktop running windows XP, a linux desktop and a linux server.

    Systems are cheap, watch for specials from the big guys and pick up a box for $399 or less.

    I haven't had to dual boot a system in over 5 years and I'm certainly not independantly wealthy.
  • If you want your stuff encrypted away and hidden from your other OS, keep it on the Windows partition. If you want to be able to share your data, make a third partition with a compatible file system and dump your files there. Problem solved.

    This article appears to be completely uninformed. Bitlocker works on a volume basis, not on an entire harddrive (unless the harddrive only has one volume). In fact, in order to get Bitlocker to work for Vista you MUST have two volumes, one being the OS volume that is encrypted with Bitlocker, and the other is the system volume which cannot be encrypted with bitlocker. Nothing prevents you from having multiple volumes and only enabling Bitlocker for some of the Windows Vista volumes. You can have other volumes/partitions with Linux or any other OS you want. The only issue is that you will not be able to read the Bitlocker protected partitions from Linux. Isn't that kind of obvious? You can still have a unencrypted FAT32 partition for sharing data between Linux and Windows, or an unencrypted NTFS partition for one way sharing between Windows and Linux (write support for NTFS on Linux is still not reliable). As far as recovery, you will not be able to do that with Linux, you will have to do that with Windows. I guess I'm not seeing a real issue here.
  • Rest assured that much of the media (video, music etc) will be in a bitlock making it impossible to transfer it to Linux or even listening to it. Its the transfering of your own data that will suffer because with Vista its no longer yours to play with if you "buy" it from any of the bigger media corps. You cant even access it with your applications of choice thanks to Vista if the corp se it fit.

    Booting wont be a problem, sharing/copying data will. At the bright side, the ability to make a very potent copy

    Seriously. we need a "Duh" Tag on this story.

    That is the entire point of Bitlocker; Encrypt the drive so only the encrypting OS can decrypt it. Bitlocker would be rather pointless if any OS could read the encryped drive now wouldn't it?

    Even if you move the bitlocked disk to another Vista machine, that machine wouldn't be able to read the disk without the decryption key, which I severly hoped you backed up.

    We're dreading this feature in Vista becuase if its anything like XP encryption and it's easy to turn on, there's going to be a lot of unhappy students when we tell them "Your hard drive crashed and all of your files are unecoverable becuase you encryped the drive"

    • Bitlocker would be rather pointless if any OS could read the encryped drive now wouldn't it?

      If any OS could read the encrypted drive given the key, then there would be no problem. The problem comes when Microsoft does not specify how to turn the ciphertext plus the key into the cleartext.

      • Yes. I agree that this should be documented and standarized. It would make recovery a lot easier, but you and I know MS is not going to do that.

        Frankly, I don't see this being a big problem for Linux because MS encryption never goes to far in any company. NTFS encryption has been around since 2000 and I've yet to see a company swear by this system. This is going to be used by people who are paranoid about what's on their drives over recovering that said data and thats basicially it, and frankly this group w

    I'm sorry, but this seems to be a bit of a non-story

    Mickeysoft can't stop anybody from boting anything. THe boot process is handled by the bios and the boot sectors on the disk, which can't be encrypted unless the bios cooperates.

    If the bios cooperates, it still has to be able to read said boot sectors, and if it can read windows boot info, it can read linux boot info, or anything ELSE you want to put in there.

    So "difficult to dual-boot" is as far as I can tell, CRAP.

    As for sharing data between the two systems ... I give it less than a month after release untill somebody has been able to figure out how to pull the data from there.
