¶Step 2:

nstalling the Linux Kernel

There are multiple ways to install the Linux Kernel in Gentoo. Either manually configure all of its features or use a pre-built one from the Gentoo developers. For our purposes, we are opting for the latter.

To install the pre-built Linux kernel, install two things – the installkernel package and the kernel itself – by running the following command:

(chroot) x8664Arch /usr/src # ln -sf linux-6.1.46-gentoo linux
chroot) x8664Arch /usr/src  # emerge --ask sys-kernel/installkernel-gentoo sys-kernel/gentoo-kernel-bin

¶ Step 3: Installing the Bootloader

From there, the final step in installing Gentoo is the bootloader, a simple program that sits between the BIOS and the Linux kernel. Its function is to instruct the BIOS to load the kernel, which then bootstraps the operating system.

(chroot) x8664Arch #emerge --ask sys-boot/grub
