In this post we create a minimal 64-bit Rust kernel for the x86 architecture. We build upon the [freestanding Rust binary] from the previous post to create a bootable disk image, that prints something to the screen.
After exploring the boot process on both BIOS and UEFI-based systems, we create a minimal operating system kernel based on the [freestanding Rust binary] from the previous post. We then combine it with a bootloader to create a bootable disk image, which can be started in the [QEMU] emulator and on real hardware.
