Multiboot Full Disk Encryption
Alright, here's my situation. I'm getting a laptop soon, and it's going to be dualbooted with either linux/vista or linux/xp (probably the former). I haven't used any form of full disk encryption before, so I'm rather new at this. Anyway, I'm not entirely sure of all the details yet, but most likely the partitioning will look something like this: Linux (ext2), Data (ext2), Windows (NTFS). All my important stuff (e.g. movies, music, work-related stuff) will be on the data partition, encryption of that is most critical, though I want the other partitions encrypted as well.
What I want is a way to more or less transparently access the linux and data partitions while in linux, and access the windows and data partitions while in windows (I'm aware I'll need to install windows support for ext2). I'd want access of the data partition to be quick/convenient from linux moreso than windows, since linux will be my primary OS. I'm rather undecided on the implementation of this. Any help/suggestions would be appreciated.
