Guide: Building and Installing a Linux Kernel from Source

Install the prerequsite

#Debian based users
sudo apt install bc binutils bison dwarves flex gcc git gnupg2 gzip libelf-dev libncurses5-dev libssl-dev make openssl pahole perl-base rsync tar xz-utils

#Arch based users
sudo pacman -S base-devel bc coreutils cpio gettext initramfs kmod libelf ncurses pahole perl python rsync tar xz

Step 1: Clone the Linux Kernel Source

git clone --depth=1 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/ && cd linux

Step 2: Copy the Current Kernel Configuration

cp /boot/config-$(uname -r) .config

Step 3: Modify the Kernel Configuration

make menuconfig  # Make your changes and save them.

Step 4: Compile the Kernel

sudo make -j8  # Adjust the -j flag based on the number of CPU cores.

Step 5: Install the Kernel and Update GRUB This step will be done tomorrow.

Don't worry your grub will be safe :)

Step 5: Install new build.

sudo make modules_install -j 4 && sudo make install

• Installs the kernel modules (from make modules) into /lib/modules/.
• Installs the compiled kernel into the boot directory (typically /boot)

Step 6: Update GRUB

sudo update-grub

• Check you bootloader config in /boot/grub/grub.cfg
