Did you check kernel folder under /usr/src?
i think you miss some steps.
In these links you will find how to Building the Kernel

you probably didn't make an initrd or forgot to compile in a key
component you need...

"make install" in the kernel source tree is a good way to make sure
there is a valid initrd...
