Dual Boot Not Trusted, Rejected By Vista SP1
Alsee writes "Welcome to our first real taste of Trusted Computing: With Vista Enterprise and Vista Ultimate, Service Pack 1 refuses to install on dual boot systems. Trusted Computing is one of the many things that got cut from Vista, but traces of it remain in BitLocker, and that is the problem. The Service Pack patch to your system will invalidate your Trust chain if you are not running the Microsoft-approved Microsoft-trusted boot loader, or if you make other similar unapproved modifications to your system.
The Trust chip (the TPM) will then refuse to give you your key to unlock your own hard drive. If you are not running BitLocker then a workaround is available: Switch back to Microsoft's Vista-only boot mode, install the Service Pack, then reapply your dual boot loader. If you are running BitLocker, or if Microsoft resumes implementing Trusted Computing, then you are S.O.L."
no, you just have to have a version of Vista that supports BitLocker, whether it is on or off. Enterpise and ultimate are the only versions that support BL, so they are the ones that need the KB which is prerequisite to SP1 install (because SP1 upgrades some bitlocker features). Never Trust Trustworthy computing. it hasn't earned it.
This *may* be a corner case as most TPM's were shipped in the disabled state back when XP was still shipping.
Instead, how about testing the open source BIOS stack? Most of you have an unused box of recent vintage and I'm sure the projects can use the feedback.
FYI: An open sourced bios is an Achilles heel for Microsoft. Mobo OEM's will **jump** on a Free bios because it saves them money and elminating TPM saves them much more money.
Get involved!!

I have Vista Enterprise on a dual boot laptop with a TPM that I have never enabled. Installing SP1 did nothing adverse to the dual boot capability.
I won't use it. I just bought a laptop on Ebay, brand new, out of box, that came with the Home edition, great bargain at $421. First thing I did with it was actually start it up and say "No" on the AUP acceptance page. I immediately powered it off, put in my trust Ubuntu Hardy 64-bit install cd, wiped the disk, and installed a real operating system that will stay the fuck out of my way.
Sorry, Microsoft, but I'd call this Epic Fail. Trusted computing causes me to lose control of *my* computer. Problem is, Microsoft don't understand the definition of computer ownership.
Linux with ntfs-3g has been supporting full read/write on ntfs for some time, and works out of the box on my ubuntu hardy machine anyways.

Two words: filesystem support.

What? You know, Linux has had full NTFS Read/Write support for a while now, see :

Also, ever heard about WUBI ?

Just games? There are lots of people who run windows as their primary OS (because it's what they are used to after spending 15+ years on a MS platform, or maybe because there are apps they rely on that aren't available elsewhere), and they dual boot Linux because they want to be able to hack around, learn more, and generally have fun.
Taking an interest in Linux does not automatically mean somebody will abandon Windows the next morning.

Informative gives Karma but Funny doesn't. Therefore, people who appreciate the post and wish to give the user some karma will choose Informative.
Beware : the new Intel ICH10R has an integrated TPM.
Intel Macs use EFI instead of a BIOS, and EFI uses GUID Partition Tables (GPT) instead of MBR.
The space that the MBR used to sit in is reserved in GPT, so when a legacy system reads, uses, or modifies the partition table, it only changes the old MBR partition table, which is not actually used to boot. In contrast, Boot Camp's dual-boot features only use the GPT, which means that as far as Vista knows, it IS the only boot loader involved.
Not at all....
Booting is handled by the EFI, and any operating system booted under the legacy BIOS emulation wouldn't be able to do a thing about it!
Its only in Vista Enterprise or Vista Ultimate, which support disk encryption.

I'm running Vista Ultimate 64bit with GRUB for Ubuntu, but BitLocker is turned off. No problems here thankfully.

Refuses to boot? Vista even refuses to INSTALL on a hdd that it doesn't believe is the "first" drive. It won't tell you why, either. It just says the partition doesn't meet its "criteria". Unplug the other hard drive and try again, and all of a sudden it works. Ignorance of surroundings is REQUIRED for a Vista installation. Use the BIOS boot selector (instead of messing with GRUB) after each individual OS is installed.
Does TrueCrypt enforce a chain of trust down to the hardware?
I believe it does. You can load any OS you want or put the disk in another machine and still not be able to decrypt the "hidden" partition, even if you know of its existence.
You misunderstood the question. TPM and full disk encryption, used in this way, ensures that every piece of software from the bootloader on up is either considered trusted or not. It starts this chain of trust in the hardware, which is considered much harder to trojan than software (like the bootloader or OS.)
Put another way, TPM conceivably protects you from software keyloggers by verifying the signature of the bootloader, the OS loader, and the OS itself before allowing you to decrypt your data. If anything in the chain has been modified, it won't release the keys, thus protecting your data. Unless Truecrypt interfaces with TPM, merely knowing the key is enough to decrypt the data, regardless of the computer that you put the disk in. Truecrypt adds a layer of deniability, but that's not the same thing.
Windows allows multi-OS booting; yes, even Vista allows it. You just have to know how to do it; just like any dual boot scenario.
False. Your solution requires hackery, while many Linux distros together with most things except Vista takes care of setting up dual-boot during the installation process.
No, they do. I think a lot of people here misunderstand what TPM is meant to actually do and what it's supposed to be good for; and what it is useless for. (Frankly, I'm not sure Microsoft fully understood.)
It's because the MBR has *changed* that means the chain isn't signed with something that will allow the system state register to authenticate with the TPM key storage; the register contents will have changed because the SHA-1 fingerprints changed, so you're not going to be able to get a coherent response from the TPM regarding any keys you've stored in it if you've taken ownership already. Without resetting the token and destroying the keys, that is.
You want another way of doing this? Don't take ownership of the TPM to store the keys, but put 'em on a thumbdrive and use a secure passphrase (10 word Diceware, for example) to unlock them; this is also a supported mode of operation under BitLocker (assuming you trust the Elephant diffuser as being part of a reasonable cipher mode; frankly, I'm not that happy with it and prefer OCB or XTS modes, or failing that Linux's aes-cbc-essiv:sha256)... doing it the "thumbdrive way" is highly recommended when a TPM isn't available or wanted. Putting the hard disk encryption keys in the TPM isn't necessarily a good idea; they are recoverable given some effort, and that's not really what the TPM tech is for.
This is all entirely by design; it's closing an actual security hole whereby a trojaned MBR could capture your encryption keys. Obviously this is unsuitable for any dual-booting setup. TPM just isn't designed to work with that kind of scenario; it's really more of a system for verifying extremely stable system images such as you might find on a server or tightly-controlled corporate workstation that you want to be able to have a reasonable degree of confidence hasn't had the MBR tampered with because it's a trusted client that handles classified data (and any tampering with the software whatsoever would decertify it).
You control the chain of trust when you take ownership of the TPM; they do work just fine with Linux, and Linux does have support for them - if you want to know and prove to another system that the bootloader, BIOS, and kernel haven't changed since the state you knew was good, you can do that (although the proof is only as good as the integrity of the TPM).
They're just hardware tokens coupled with a signed BIOS/bootloader/kernel, really. Handling the actual key management that results from that, or what you do with it, is entirely up to you.
Vista using the TPM for BitLocker is hardly plug-and-play, and quite unsuitable for many scenarios (many TPMs out there don't even support TCG1.2); there's always TrueCrypt or PGP Whole Disk Encryption or one of the many other solutions available if you want a little more flexibility and control.
In particular, it's not really about DRM. None of the DRM systems proposed or deployed have ever used it, or are likely to ever use any part of it, as a key storage blackbox, because an entirely homogeneous image just isn't something you can guarantee on any consumer box (that's one reason it's not even on or in the vast majority of OEM and consumer motherboards/chips). It's perhaps a bit more practical for laptops...
Also, TPM implementations are quite breakable where the attacker has physical access and ownership of the machine and plenty of time. PCs aren't even consoles, and look what we've done to those...
It's meant to be one interlocking part of a whole enterprise security solution. It sure as heck isn't a "magic crypto chip" that will lock up your PC, and it shares none of the common criteria with DRM scenarios (which are, of course, just as doomed if they use a hardware blackbox as if they use a software blackbox, because the plaintext is always available...). In fact, having a TPM around if you're running Linux, will at least make sure you always have a secure entropy source for /dev/random...
Informative has the benefit of generating a "Why is this informative!" post, which leads to people replying "Informative gives Karma but Funny doesn't. Therefore, people who appreciate the post and wish to give the user some karma will choose Informative." and getting rated Informative, which generates Karma itself.
It's kind of a huge karma circleje-..dependency.
Too right, I just modded it informative too, and your post as well, so your ka... oh wait. whoops.
What if Tetris was invented by Nazis?

This should definitely be modded Informative.
I'm so excited I just made water in my pantaloons!
I think the point is just to be nice :)
It's because what people are really saying is +1 satire./P
Oh, well heh, I think modding someone funny for being funny is nice enough for a little o' that real life karma. :)

So "informative" is the new "funny"?
Damn!
Oh no! You guys started an infinite Karma loop!
Modern copyright is theft of culture from everyone and it retards the progress of the useful arts and sciences.
I have Vista Enterprise in a dual-boot laptop with TPM and grub as the primary boot loader, and SP1 installed without any problems at all, and never altered the boot loader. It's 64-bit Vista, which is typically even more stringent with the code checks than 32-bit.
Were Microsoft not attaching it to a KB article, I'd have called it FUD, but I will say that I have not experienced it at all.

Dear sir, if you find my posts funny, please mark them funny so that I know you got the joke and don't think you got confused and took me serious.
I don't give a fuck about karma. Anyone willing to make the effort can have theirs pegged at the cap if they wanted, anyway. (Karma whores don't deserve it, and those that don't care about karma and just post things that are interesting and informative are always at the cap anyway.)
The cake is a pie
First, note that Iam the story submitter.
Second, and more important, note that I am a programmer and have I read the Trusted Platform Module technical specification from cover to cover. The 332 page technical spec.
The goal is to allow you to trust that your computer has not been compromised by a third party
Demonstrably incorrect. That is NOT the fundamental design criteria of the Trust chip.
You could get all of that functionality from a virtually identical design that did not secure the computer AGAINST the owner. If you are up for the technical details, you could for example have an identical chip with identical capabilities, except that you permit the owner to get a printed copy of his PrivEK when he buys the system. That alone would be minimally sufficient to grant the owner ultimate control of his system, but for technical reasons the chip should also have the capability to export the RootStorageKey encrypted to the PrivEK, as this makes things massively simpler benefiting security.
I forget the page number, but at one point somewhere in the latter half, the technical spec EXPLICITLY refers to the the owner as an "attacker". The specification explicitly details the measures that must be taken to secure the system AGAINST THE OWNER.
AGAINST
THE
OWNER.
Q.E.D. The fact that the technical specification for the chip repeatedly places the HIGHEST PRIORITY of forbidding the owner to ever obtain his own key (which would provide him ultimate control of his own computer) demonstrates that in fact the purpose of the design is to secure the computer against the owner. As the grandparent put it:
Trusted computing is all about allowing vendors like microsoft to trust the computer to work in thier partners interests rather than the users.
Of course, if you pour concrete over my house and take other insane measures to lock me out of my own home, yeah.... that does also incidentally have the effect of keeping other people out of my home too. The point here is that the owner is denied the key to his own house. Trying to advertise that as a security system securing the home FOR the owner is obviously a comically bogus argument.

"intentional way of censoring what somebody considers a really sensitive topic"
I've also suspected this is possible a number of times. Companies like Sony, for example, have been shown up for using such tactics as Gorilla Marketing, to get their message across and employing bloggers to appear to be independent reviewers, when in fact they are working as part of an organized PR campaign So its well within the concepts of Gorilla Marketing style behavior to work to manipulate popular forum discussions. I wouldn't be at all surprised if many big companies and even some governments could be playing these same disinformation style games. Its interesting how manipulations to the Wikipedia have been detected and proven to be occurring. Forum style discussions need some way to detect organized disinformation/manipulation campaigns, but that's not going to be so easy to detect, but over time, at least more people are becoming aware of these disinformation games.
There are 10 kinds of people in the world... those who understand binary and those who don't.
The nasty thing isn't that Funny doesn't give karma, it's that Overrated and other downmods still take away karma on a post marked as Funny. So, if a post gets moderated up to +5 Funny, then gets two Overrated downmods, the poster loses karma overall. Over time, this can eat away at someone's karma, especially if they're writing a lot of humorous posts that don't go down well with everyone.
