Build And Install The Kernel

To build and install the kernel, execute these three commands:
make oldconfig
(make prepare)
make modules
make all
make modules_install
make install



make -j2 bzImage



give descriptive name

mv /boot/vmlinuz /boot/vmlinuz-4.7-custom

Create an initrd file. Again, adjust the filename to match the current kernel version:

1	mkinitrd /boot/initrd-4.7-custom.img /boot/vmlinuz-4.7-custom

make modules
make 
make install
make modules_install
