Hello. I have been dual booting Ubuntu and Windows 7 for a while now. In the past, I have used the "encrypt home folder" option to add (some) security to my installation (ie. now no one can easily steal my home folder's contents by booting a live CD or using Windows to access my Ubuntu root partition). This is why I was excited to learn about the new Full disk encryption option in 12.10. I was able to successfully burn and boot the DVD. However, disk encryption and home folder encryption are not available options under "install along side them [the other operating system(s)]". Since I do not want to lose the Windows installation, I obviously do not want to select "erase disk".
Basically, here is what I would like to happen:
Power on > BIOS > GRUB > user choice (Windows or Ubuntu)
User Choice (Windows) > Non-encrypted, normal Windows (no encryption pass-phrase required)
User Choice (Ubuntu) > Encrypted Ubuntu 12.10 installation (with pass-phrase required)
Now, I am able to access the "Something else" custom option, but I want to make sure I am doing everything right here.
My current partition setup looks like this:
/dev/sda1 is a small NTFS claimed by Windows (boot related??)
/dev/sda2 is the very large, main Windows partition
--16GB free--
/dev/sda3 is manufacturer recovery
So, I think I need to create:
1. a /boot partition (small, less than 100MB)
2. a "physical device for encryption" (within which / will be)
3. a swap partition
I have some questions, namely:
A)Will this work as intended? and
B)What sizes should I use for these partitions (I have 4GB RAM, but running out of memory has not been much of an issue in past installations.)?
