full disk encryption

Thanks for your answer my menu.lst seems ok, and the uuid looks good (it is the same on /dev/disk/by-uidd/**)But when I try booting whithout chroot, when I am on the emergency shell, there is no /dev/disk/by-uuid For the mkinitcpio.conf, I don't know : it seems good too but ... I never had to change it to boot with this computer.

I'm installing Ubuntu using the alternate installation CD.

I would like to do full disk encryption, and I have two questions:

1. Is the following option the correct one for Full Disk Encryption with pre-boot authentication?

Code: Partitioning method: Guided - use entire disk and set up encrypted LVM 2.

I've got SIFT (based on Ubuntu 9.10) installed on a work laptop. We're trying to encrypt the entire installation (root partition and swap), which is apparently doable using LUKS, but I'm having some trouble getting it all to work.

Here's where I'm at so far:

I have an unencrypted /boot partition, one unencrypted root partition, and one encrypted partition.

I have a ubuntu 12.04 64 bit system, where I have two sda partitions sda1 and sda5, sda1 is unencrypted ext2 boot partition and sda5 is lvm2 encrypted disk with root filesystem and home etc.

Till yesterday I was able to login and was working fine. Today onwards I was not able to login(no typo mistake),login always fails. Passphrase and decrypt is going through, but login fails.

I just run into the same problem. However, I had to edit /etc/mkinitcpio.conf and add the support for lvm2 :HOOKS="base udev autodetect pata scsi sata lvm2 filesystems usbinput fsck"The source of the problem may be with the hook autodetect.

Currently I'm using EncFS to encrypt my directory "confidential" to ".encconfidential" and sync that encrypted directory using an online service (e.g. Dropbox, UbuntuOne etc). However my entire disk is already LUKS encrypted, so the double encryption takes a toll on performance.

I wonder is there an "inverted" EncFS option?
