Bootloader

A bootloader for UEFI, like a BIOS, is designed to boot the entire system and display configuration options for the kernel.

Creating Your Own Bootloader

Creating your own bootloader for UEFI or BIOS takes over 10 years or more; creating a minimal, working bootloader takes several months. Therefore, we'll make do with the open-source bootloader from Syslinux

To get started

Before starting, you can read and look at the code for Syslinux or even create your own or edit the one from Syslinux and compile it. If you're not interested, we'll use a pre-built bootloader for UEFI and BIOS.

Create a structure before yours for the kernel itself.

To do this, create a boot or another name for Bootloader:

Terminal

Then copy the prepared files for UEFI and BIOS:

  • In boot, enter:

wget https://www.kernelstepbystep.pp.ua/bootloader/bootloader.txt

  • Once you have the file:

wget -x -nH --cut-dirs=1 -i bootloader.txt

  • Once all the files and the structure have downloaded, delete the file with the links:

rm bootloader.txt

The resulting structure should contain the main files for loading BIOS (Syslinux), and for UEFI, there will be an EFI folder, then Boot, and then Syslinux for UEFI.
