LinuxBoot is a firmware for modern servers that replaces specific firmware functionality like the UEFI DXE phase with a Linux kernel and runtime. Thus far, LinuxBoot could only launch unix-like OSes via kexec and did not support any OS that relies on the EFI standard. In this session, we demonstrate our proof-of-concept utility that can kexec the Windows EFI loader. The tool is based on the u-root project and modifications to the Linux kexec syscall. We will demo a successful launch of Windows 2019 using LinuxBoot/u-root.
