I was wondering how to successfully use the hidden OS encryption feature of Truecrypt with Vista/Seven. It requires that there be a partition before the OS partition, and in moving my partition which is an oem default disk location, I could no longer use most of windows' features. The thought is that they are still trying to call on default location, which has been moved up on the partition table to drive d: from c:. I was wondering if I have to alter environment variables in order to use this feature, or just install Windows without using the factory get-up? My restoration disks don't provide an option for this. Thanks.
