I prefer to use Linux software for a lot of reasons. But sometimes I need to use Windows, so I have both of them installed on my laptop. It took me much time to find out how to encrypt these two and still dualboot them.
Well, I found out how and wrote an article about it. It starts with some background information about disk encryption, partitioning, boot sectors and bootloaders. I wrote a comprehensive guide how to encrypt Windows as well as Ubuntu and added a lot of screenshots and comments to it. Finally you’ll find some tips and troubleshooting subjects that addresses repairing of boot failures and other convenient facts.
I hope you have a lot of fun with this multi page article.
