To avoid this challenge, weвЂ™ll use C++ as the main language for low-level programming in this bootloader development tutorial.ДЄlso, knowing the basics of how to work with an assembler is a great advantage when writing a bootloader.

You canвЂ™t use runtime-dependent languages like Java and C# because they produce intermediate code after compilation. When developing a bootloader, you need a language that doesnвЂ™t depend on the runtime. The only exceptions are hypothetical cases when you implement all required runtime code by yourself using some set of native languages.

You can execute that intermediate code only after itвЂ™s converted. Most commonly used languages use a virtual machine to convert intermediate code into language understood by the processor.

Secondly, all UEFI-compatible systems can behave like BIOS systems in legacy mode, so youвЂ™ll be able to run our bootloader on UEFI systems as well. Furthermore, almost all old devices support BIOS only. The first reason for this is because BIOS is supported by a wider range of hardware. Secure boot verifies that a device boots using only trusted software that has electronic signatures.Д«ut despite all these advantages, in this tutorial, weвЂ™ll be developing a BIOS bootloader from scratch.Writing code directly in C using complete development environments such as EDK2 eliminates the need to study assembler or mix high-level and low-level code.No boot disk size limitations allow you to use any disk to boot the system.The ability to work in 32/64 mode allows you to access more processor functionalities, while BIOS works in 16-bit mode only.Key advantages of working with UEFI instead of BIOS: UEFI is a modern BIOS replacement provided on modern hardware that gives developers many more options for low-level development. A BIOS is well-known computer hardware supported by all devices.

You can develop a bootloader for a Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI). Choosing a firmware interface: UEFI vs BIOS But keep in mind, that a boot sector is required only for BIOS-based systems. So for now, weвЂ™ll stick to the first sector as well. This isnвЂ™t obligatory for a modern boot system, but most developers place the bootloader in the first sector. The boot sector is usually the first sector of the disk. When the firmware finds the bootloader, it loads it and the bootloader initiates the launch of the OS. Computer firmware reads the data contained in this first sector and processes it to the system memory when the machine is powered up. This sector is also known as the master boot record (MBR). LetвЂ™s start with a quick overview of bootloader development basics.ДЄ bootloader is a piece of software located in the first sector of a hard drive where system booting starts.
