Problem with newly compiled kernel 2.6.39 (initrd.img not being created)

Problem with newly compiled kernel 2.6.39 (initrd.img not being created)

[Naman shekhar Mishra]

My platform is Intel 32 bit. 

I am using kernel 2.6.35-22 generic for these steps and the newly compiled kernel is 2.6.39

Here's my steps:
$make defconfig

$make -j2 CC="ccache gcc"
$make modules
#make modules_install
#make install
#update-grub

After these sequence of steps, I tried to boot into the new kernel and there was nothing (except for the blinking caps lock) .So I checked and there was no initrd.img in /boot. So I tried using mkinitranfs and it created the ramdisk and then I booted but still it won't work.
Though I can boot into recovery mode but the shell prompt is strange like (initramfs)...

Typically, I precede with 'make mrproper', but AFAIK it won't make a
difference if you are compiling a brand new source tree, and doing so
_within_ it (ie without a separate build directory.)

I always go over the resulting .config anyway, to ensure -- though I
admit that that can be very time-consuming if you have not done it
before.

Typically, when I am getting an 'initramfs' shell-prompt, I have to
tackle issues other than mkinitramfs. The solution has (IIRC) always
been to add missing options in the .config file. The lines immediately
preceding the shell prompt give a hint as to where things (eg which
options) croaked!

try to preceed it with "make mrproper" first...just to make sure you
don't inaccidentally use leftover object files from previous
compilation....

try to leave out ccache temporarily....... just to make sure you use
freshly compiled object files.

I am not 100% whether "make install" implies "make bzImage".
Personally, I suggest this order:
make bzImage
(check whether you indeed see arch/x86/boot/bzImage....)
make modules && make modules_install
make install

Simply blank? no previous message? even grub's kernel selection screen?

that may or may not be the source of the problem.....
