Will Windows Vista (Bitlocker/Bitlocking) allow multi OS boot ?


Hi Guys,

Does anybody know If Vista works ok with Linux machine.

Say - I have A linux box and wanted to check out Vista But considering Vista Boots different way then XP and so forth.

So after installing Vista, Even If "GRUB" again - would you know if linux partition comes up ok.


Secondly what if you fool around with Vista Bitlocker. Will it allow Linux to co exist.

Why don't you experiment to get the scoop? If you make a full copy of your HD with say Partimage you're safe...

Honestly speaking - I can do that - But I dont have any Windows Operating system installers / Vista disc.

I was just curious as I was going through this link :

http://www.microsoft.com/whdc/system...LockerFAQ.mspx

This part of information made me think this :


Quote:
What changes would cause the integrity check on my system to fail?


Unauthorized changing of the BIOS, master boot record (MBR), boot sector, boot manager, or other early boot components would cause a failure in the integrity checks and keep the TPM-protected key from being released. This is by design because unauthorized modification of any of those components could and should be perceived as an attack. Of course, the BitLocker feature provides methods for authenticated system administrators to update these components if required.

If you have Bitlocker enabled then it will be a pain in the butt, but not impossible to dual boot linux/vista. However you will no longer be able to read/write from/to encrypted drives.

See this article on DesktopLinux.com for more info..

That article is good read.
I am not convinced for primarily two reasons (Non technical)

1. In given article author "merely" thinks. there is no conclusive proof otherwise - say he tried Bitlocker and dual/multi boot on his box.

2. As per my earlier quote - and MS link there - it specifically uses words like "mbr"/bios etc


And I did a google and this is what I got :

where in it appears that windows does lays down a new boot sector to avert virus threat.

1.http://blogs.msdn.com/oldnewthing/ar...20/505887.aspx


Microsoft really wants to discourage Linux users and with Vista its more obvious then ever. you may ask why - Well, If you have Windows XP installed - Vista detects that earlier os and will make appropriate changes to boot loader - but if it were non MS Os in that case - It will all be gone. All you are left with MS boot/OS.

Now with this Link http://blogs.msdn.com/si_team/archiv...-Security.aspx

* Early Boot
* Mid Boot
* OS Boot

If guys have read this commet this further here are a few expanded acronyms

full-volume encryption key (FVEK)
Trusted Platform Module (TPM) http://en.wikipedia.org/wiki/Trusted_Platform_Module
platform configuration register (PCR)



For more on MS related acronyms/glossary
http://download.microsoft.com/downlo...erGlossary.doc

Of course you can do google for more information

Now for Scoop

http://lwn.net/Articles/144681/ Which talks about TPM and linux / Linux and trusted computing.

I am still clueless
