An interactive UEFI boot manager that aims to be light and easy to use.
This boot manager is being developed using the POSIX-UEFI wrapper library.
- Very lightweight.
- Simple and easy to use configuration.
- Shell environment with useful commands.
- Text editor.
- Able to boot operating systems and UEFI apps.
- Can automatically detect a Linux kernel along with its version.
Arch (pacman): make clang lld efibootmgr
Debian (apt): make clang lld efibootmgr
Gentoo (emerge): sys-devel/make sys-devel/clang sys-devel/lld sys-boot/efibootmgr
Run make in the root directory of the project to create the boot manager's .efi file.
The boot manager is unsigned at the moment and you will have to disable secure boot in your bios or sign it yourself.
The boot manager fully supports the x86_64 architecture. Compiling for aarch64 is possible, but untested. It is possible to change the architecture to aarch64 by editing the Makefile in the root directory of the boot manager source code and changing the ARCH variable.
Clang is the preferred compiler for compiling the code and it will be used if clang is installed, but gcc can also be used.
If you have clang installed and want to compile with gcc, add USE_GCC=1 into the Makefile in the root directory (before the include line). If clang is not installed, the code will be compiled with gcc automatically.
Compiling this project with gcc+ld is not supported and it may not work, do that at your own risk.
See EMULATING.md for instructions on how to run the boot manager in QEMU to test all kinds of code changes quickly and easily.
To install the boot manager, simply run the installer script (installer.sh) as root. A new boot entry will be created with efibootmgr and the boot manager will be run the next time the device is started.
To update the boot manager, run make distclean && make and then run the installer script again. The configuration file will stay unchanged.
See CONFIGURING.md to see how to write the config file.
