Use fastboot to flash boot.img from the CM11 thread. The FXP one. Youll find it in the original development section. Or you can download directly from FXP. Once you flash the boot.img from the zip file through fastboot. Flash the ROM via clockwork recovery included in the boot.img. Dont forget to copy the FXP cm11 beta 3 into your sdcard before flashing.
You can reply to this thread incase you need a more detailed tutorial on it.
