But look at you (I'm assuming you are the original poster now under a 
differnet name), you ask about the kernel, but then go off about grub2.
It's still not clear where your problem lies, the two are distinct.  You 
should be playing with multiple kernals that are already compiled, like 
from your distribution, then play with grub2 to make a multiple boot 
system.  Once you get that figured out, you can go on and compile kernels.

In the old days, it was almost mandatory to compile the kernel for a new 
system.  You needed to have the right drivers for the hardware you had, 
and maybe more important, you didn't want a bloated kernel.  Now, it's 
mostly all included, and the "average" computer has so much RAM and 
hardware space that a large kernel doesn't matter.

So at this point, anyone wanting to compile a kernel is doing it for some 
specific need, maybe the challenge, maybe they have some obscure hardware, 
maybe they are just interested in making it smaller.  But most people can 
live with the bloated kernel that comes with any distribution.

Even when compiling a kernel, most people are just customizing.  They 
aren't writing new bits to the kernel, or modifying the code, they are 
simply telling the compiler to produce a selective version of the overall 
kernel.

If you know nothing of initrd, then you need to read up on it.  It 
provides some things during the boot process.  Modules are a different 
thing, it allows one to adjust hardware without having it all tossed into 
the kernel.

And one thing to watch is that some distributions apparently fiddle with 
the kernel, so if you don't use their source, you end up with a 
non-working system.  While other distributions, like slackware, use the 
off the shelf kernel, so one can pull from kernel.org (with the warning 
someone pointed out, you can't mix and match a kernel with the libraries, 
there is a level of interaction).

But I see no indication that you are ready to be compiling a kernel.

Get grub2 going.  You can even do that with the same kernel, duplicate it 
and then get grub2 to select between the two kernels, you'll see no 
difference but if you are doing it right, the system will boot with 
either.

And dont' expect hand holding on the part of the distribution.  Compiling 
kernels is now esoteric, so you won't find a utility that compiles and 
sets up grub2 all in one operation.  You need to learn first.

No, but it involves learning and trying things, and actually doing work.
