Re: BitLocker Post OS-Install - Boot & Partition Considerations
Per Josh, this is a really cool tool coming from the BitLocker Team (I'm now
on another project, so you'll probably be hearing less of me).

Reconfiguring a disk to get BitLocker working... without causing problems
later / rendering machine unbootable, requires a large number of steps a
number of which involves BCDEDIT. I'm amazed Banquo had success.

I really recommend holding out for the tool rather than trying to jump
through the reconfiguring hoops.
