I will assume you have a 16 GB drive with no other partitions.
I select it and on the next screen, I select Create a new partition.
This is going to be /boot and I set the size to 16MB and select primary.
On Partition settings screen, I choose Use as Ext2, Mount point /boot, and
Bootable flag on. Then I choose Done setting up the partition.
That is much too small. The Wheezy machine I'm typing on has 512 MB for
/boot (~18 MB used). Why ext2? I use ext4.
Next I select to automatically partition the remaining free space that
results in two logical partitions 15.1 GB ext4 mount point / and 693.1
Don't select automatic -- do everything manually. You want to create a
second primary partition at the beginning for swap (I allocate 512 MB),
use it as physical volume for encryption, with a random encryption key.
Then create a third primary partition at the beginning for root (I
allocate 13.4 GB), use it as a physical volume for encryption, with
passphrase encryption key. Then configure the encrypted volumes.
sda2_crypt will end up as swap. Then configure sda3_crypt as as root.
