I've learned the hard way that there are lots of gotchas that can
generate that message, and they're not all too obvious. The basic
things to look for - mobo and HDD drivers and fs support builtin to the
kernel (not as modules since you aren't using an initrd? Same for
lvm / luks / raid or anything else needed to get your HDD online?
You should probably give us as much information as you can about your
setup, with regard to the above questions, and post your kernel config
somewhere, perhaps a pastebin.

Celejar,
You were right. I need to set my PCI drivers to be built-in instead of modular, along with the file system drivers. That fixed it.
