Managing EFI Boot Loaders for Linux: Using fallback.efi

 · The EFI handover protocol cannot be used by EFI firmware because the entry point does not use the EFI application ABI, so a Linux boot loader is required. Internally, jumping to the EFI handover protocol entry point still handles early device discovery, saving of the EFI memory map data, and termination of the Boot Services.The first line should be the filename and location of the kernel to be booted relative to the root of the EFI system partition, e.g. EFIKernel1MyKernel.64 or SocksBubbles.ReallyLongFileExtension (do not use spaces or special characters in file/folder names), and the second line is the string of load options to be passed to the kernel, e.g ... · This page is part of my Managing EFI Boot Loaders for Linux document. If a Web search has brought you to this page, you may want to start at the beginning. What's the Problem?
