Comment 0 for bug 1187660

Users require the ability to partition to different sizes other than the full disk capacity.

As of version 2.14.6, Ubiquity still lacks basic manual partitioning functionality. Using Ubiquity it is not possible to manually configure logical volumes inside a physical volume for encryption. This functionality last existed in the alternate cd release in Ubuntu 12.04, since discontinued as of 12.10.

"The manual configuration partitioner should at least be as featureful as the alternate CD partitioner. When you create a new partition and choose the type, the list should include "physical volume for LVM" and "physical volume for encryption" as well as ext4, ext3, fat32, etc."

"If you want to dual-boot Ubuntu and Windows, your partitioning scheme can look like this:

/dev/sda1 - NTFS for Windows
/dev/sda2 - ext4 for /boot
/dev/sda3 - physical volume for encryption volume

Within the encrypted volume you can set up a "physical volume for LVM" and within that create two volumes, one for swap and one ext4 for /. If someone already has Windows installed, Ubuntu can use free space on the drive to automatically create a /boot partition and put everything else in an encrypted partition."
