Kernel panic on boot after recompiling kernel

[thecell]

Hi.
I'm writing because I've a problem when I compile my kernel.
I've Red Hat Enterprise 4 (now my kernel is 2.6.9-22). I downloaded kernel 2.6.27.18 from The Linux Kernel Archives. I used these commands (as root):

cd /usr/src
tar -jxvf /home/thecell/Desktop/linux-2.6.27.18.tar.bz2
cd linux-2.6.27.18
cp /home/thecell/Desktop/config-2.6.27.18-mykernel .config   # I already have a config file to compile
make
cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.27.18-mykernel
make modules_install
cp .config /boot/config-2.6.27.18-mykernel
mkinitrd -v /boot/inird.img-2.6.27.18-mykernel 2.6.27.18-mykernel
cp System.map /boot/System.map-2.6.27.18-mykernel
cp vmlinux /boot/vmlinux-2.6.27.18-mykernel

I edited /boot/grub/menu.lst for my new kernel.
On booting, the result was:

  Booting 'Red Hat Enterprise Linux (2.6.27.18-mykernel)

[    5.516193] Kernel panic - not syncing: Attempted to kill init!

Moreover, I want to say that i'm not an expert, that when I installed red hat I used default partitioning suggested from red hat (but I know something about partitioning), and that i'm using vmware. I hope you can help me, because i searched in the web, but i didn't find anything that resolved my problem.



P.S. Sorry if my English isn't perfect

Ok, I renounce...
I won't recompile kernel...
