Guides to compile the Linux kernel from source, create the file system from BusyBox and then run it using QEMU. But, Create a bootable ISO of it and boot it on a computer.

The Linux Kernel

wget https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.7.1.tar.xz
tar xf linux-6.7.1.tar.xz
cd linux-6.7.1.tar.xz

General preparation environment to compile the kernel...

sudo apt install build-essential libncurses-dev bison flex libssl-dev libelf-dev

To configure the kernel: 

make defconfig

This will create the default config file for compiling Linux. Then run 

make menuconfig

to enter a TUI to edit the config file. One thing for older devices is unchecking 64 bit kernel.

# Example: Using 4 parallel jobs
make -j4
