Hey folks,
I've had my very first Apple computer - a MacBook Pro - for about 8 months now (and what a computer! Love the design, hardware, operating system... This is definitely an Apple fanboy in the making
) and until now I have been using the basic Boot Camp set up + rEFIt to run Windows.
I will be traveling soon and I think it would be a wise idea to properly secure my data. TrueCrypt is installed in both Leopard and Windows, and I want to take advantage of TrueCrypt's hidden operating system feature to encrypt the entire Windows system drive and install a decoy operating system. This seemed straightforward until I learned that TC requires Windows to be the first partition on the drive, and that's where the problems start...
The guide at http://blog.taggesell.de/index.php?/archives/36-TrueCrypt-on-Macbook-Windows-XP.html explains how to do this but the result is an MBR-only drive, and as I understand it Apple's Software Update won't work without a GPT drive and the EFI system partition.
It would seem the only viable way of doing what I want is to stick with the GPT/MBR hybrid that Boot Camp creates, with the Windows volume being the first on the disk (i.e. before the EFI volume). Using gpt, diskutil and GParted, I have come up with the following setup as reported by rEFIt's Partition Inspector:
I think I am almost there, but as can be seen from the above report the MBR partition table is invalid. rEFIt refuses to fix this.
Is there a way I can manually edit the MBR table to correct it myself?
