I have created this page http://martin.hinner.info/fs/truecrypt/ couple of months ago.

Grub-install destroyed my Win system-encrypted windows (it's bootloader). I have recovered it, however I wasn't able to boot to Linux using GRUB then. Problem was with overwritten track0 of my boot disk (where grub likely placed stage1.5).

I think it would enormously help if grub is not installed only in MBR, but also in boot sectors of / and /boot. Plus it should automatically save a copy of MBR and track0 (both separately!) to /boot/backup/mbr-date.bin and track0-date.bin. Having a backup is always a very good option!

Then you can put grub.bin (=boot from / partition) to BOOT.INI in Windows and boot it from there. Or install grub properly and switch between truecrypt and grub.

So solution for skilled people is to have grub not only in MBR and have install-time backup of mbr and track0.
