How do i know if i encrypted the disk when i installed kubuntu 10.10?

I'm trying to secure my dual boot machine from thieves and non authorised uses and i can't recall if i encrypted the whole disk or just the /home partition. Is there a way to know if i did it? Is there a secure way to make the laptop boot into windows unless you have some password?

From what I can tell, the best way to check would be to get a LiveCD/USB and run it on your box. When it loads up, attempt to access your files through the browser[if they are not encrypted, you will be able to do this]. Another way is to go into the other partition and attempt to access it from there as well. If neither work, you can be fairly confident that it is encrypted properly.

if your /home/<username> is encrypted there will be a directory called /Private, as well as /.ecryptfs

You can set a grub password, but i don't know of a way to do it per menu entry. You also can set it to boot windows automatically instead of Linux (or whichever you choose).

Well looks like i was wrong about the per-entry passwords

that might be what you want to try there.

I didn't find that folders so it seems obvious that / and /home aren't encrypted. What is the best way to encrypt all linux partitions when you already have a system installed?

should get you started. There are a number of other links in the wiki on the subject, but though probably good info-wise, most are for older versions and could be outdated.

Do note that the .ecryptfs and is a hidden directory in /home, not /home/<username>
and .Private is also a hidden folder in your /home/<username>

Encrypting your /home/<username> directory tree is possible, although I'd be concerned about the (pseudo) hidden ".whatever" (where "whatever" is a program name) files and directories that hold your personal preferences for the programs you use. However, I believe, that encrypting your software, is a VERY bad move for a number of reasons.

If I were either paranoid, rich, or a spy for a foreign power, I would simply encrypt all the files in my /home/<username>/documents/ directory tree. This would leave me with a usable, fast computer that I could upgrade efficiently. If I were an enemy spy, (or if I were still doing classified work) I'd keep all my personal files on removable media that I kept in a (security agency) approved safe/file cabinet whenever I wasn't using them. This computer would NEVER be exposed to the internet.
