GRUB is a bootloader. </p> <p>By using a boot loader over a boot menu, you alleviate alot of the early angst hobbyist OS programmers usually get when trying to load their kernel. The boot loader loads your kernel for you, regardless of filesystem. Good boot loaders also recognise some executable fileformats. </p> <p>If you ignore using a boot loader, you have to write your own loader to read in your kernel file from the file system.</p> </TD> </TR></TABLE></body></html>⌨️ 快捷键说明
