Hi Rahul,
The directory /usr/src/linux contains your current kernel and if you try to install the kernel into that directory, you will mess up your current linux kernel. So the person who told you not to install is absolutely right,because there are a lot of dependencies involved in a linux kernel. The linux kernel is written in C language. In most languages you need to convert you code into an object file which is what compilation of a kernel does. Installation refers to a doing a lot of things which will help your kernel boot up, like editing the grub configuration, creating a ram disk for boot, copying your kernel image to /etc/boot, etc. So this process is totally different from compilation. And yeah, if you install your kernel elsewhere you will have two kernels in your system, which is why i suppose you are installing a new kernel. Its always better to keep the old kernel as it is, especially the first time, to avoid any unforeseen problems. Hope your doubts are solved.
Regards,
Prathamesh
