Be careful some of those windows encryptions will make it difficult if not
impossible to have a linux partition that will boot.
That said - if you can boot linux then this may be helpful. I actually went
the other way, i deleted windows when I encrypted my laptop disk!!
I have encrypted /home and swap. To deal with /tmp and /var/tmp leakage of
information I remount (mount --bind) these from the encrypted /home
partitition. Knowing all I do today, I would avoid ancrypting root
partition - it adds little additional security (some yes) but can be
problematic if you run into problems (ie cant boot).
Basically i use /etc/crypttab to encrypt swap but this did not work
correctly for me for /home so I hand scripted it (its trivial to do).
For some info see :

Cant speak for F8 but encrypted root on F7 will not work until mkinitd is
updated (see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=124789 for
some discussion). I believe (k)ubuntu does this out of the box - however as I
said above I'd avoid encrypted root.
good luck.
