In the Document -> Settings... -> Document Class -> Document class drop-down list, do you find book(KOMA-Script) listed as unavailable? If so, either the scrbook class is not installed in your LaTeX distribution (MikTeX?) or for some reason the LyX installer failed to find it. You can check whether it is installed by running 'kpsewhich scrbook.cls' at a command prompt. If it is not installed, and if you are using MikTeX, just use the MikTeX package manager to install it.
