I currently download the 6.3.4 version of the kernel a multiple other versions as well. I am not able to find the boot folder or the .config file. Can someone please help me out here?

Hi,
would be nice to give us more details. What did you download exactly, from where? What did you do with that downloaded file? The boot folder is usually located in / (so it is /boot). What do you want to achieve at all?

If this is kernel source code, you make the .config file yourself by running a suitable "make" command: I use "make menuconfig" but there are others ("make help" will give you a list). Browse around the tree and use the help command to inform yourself about the meaning of all the options. Mostly you have the choice of compiling something right into the core of the kernel, compiling it as a separate module, or omitting it. You can omit drivers for hardware you don't have, which will shrink your kernel considerably, but keep the defaults for anything you aren't sure about.

When you exit from this stage, you will have a .config file ready and waiting! You can then use "make bzimage" to compile your core kernel and "make modules" to compile the module collection.

The boot folder appears after compilation, and your kernel will be in there under its architecture code.

I downloaded https://cdn.kernel.org/pub/linux/ker...x-6.3.4.tar.xz from kernel.org. I decompressed the downloaded file. I want to build my own Linux image.

Try reading https://wiki.linuxquestions.org/wiki...n_Linux_kernel.

I have read the wiki but I am unable to locate /src directory in the kernel folder I downloaded from kernel.org. I am unable to do anything since I don't have all the necessary files.

The source will be put in a folder linux-6.3.4 (or similar). There is no /src.

I figured out what I need to do. Need to run makemenuconfig.

Nope! It's "make menuconfig"
