An experimental x86_64 bootloader written in pure Rust that works on both BIOS and UEFI systems. It lets OS developers package their Rust kernels into bootable disk images with minimal build-time dependencies.
Use cases
- boot a custom Rust kernel on BIOS and UEFI systems
- create bootable disk images from compiled kernels
- write a hobby operating system in Rust
- get memory map and framebuffer info at kernel startup
- build an OS without assembler or C toolchain dependencies
When to choose
- you are writing an x86_64 kernel in Rust and want a ready-made bootloader
- you want to support both BIOS and UEFI boot from one codebase
- you want a bootloader buildable on any host platform with just rustup
When to avoid
- you need a production bootloader for non-x86 architectures
- you need multi-boot or chainloading features
- you need a battle-tested bootloader for a commercial OS
