I have a Samsung Notebook NP900X4C with an LUKS encrypted installation of Linux Mint 15 on it. The system is booting in UEFI mode.

The problem is that the samsung-notebook kernel module is disabled in UEFI mode and due to that I am missing features like the keyboard backlight.

Is it possible to modify the current installtion so it can boot in BIOS mode?

Is this correct that the basic steps would be converting the disk from GPT to MBR and installing grub from a live CD? Would this be possible with a LUKS partition?
