I have recently bought a new laptop and installed Xubuntu 15.04 on it right away. I store some sensitive data on it, so I checked the "Encrypt the new Xubuntu installation for security" and "Use LVM with the new Xubuntu installation". Then I found out that many games I like don't work with Wine, so I decided to install Windows 7 as dual-boot.
My question is - can this be done simply by resizing the Xubuntu partition and installing Windows on a new NTFS one? Or would this require backing up all the data, formatting the drive and reinstalling Xubuntu unencrypted, then Windows?
