LILO<\/strong> and GRUB<\/strong> are boot loaders<\/strong> used in Linux systems.
A boot loader is a small program that loads the operating system kernel into memory when the computer starts.<\/p>\n\n\n\n

\n\n\n\n

1️⃣ LILO<\/h1>\n\n\n\n

LILO<\/strong> stands for Linux Loader<\/strong>.<\/p>\n\n\n\n

🔹 Features:<\/h3>\n\n\n\n
    \n
  • One of the earliest Linux boot loaders.<\/li>\n\n\n\n
  • Loads Linux kernel from hard disk.<\/li>\n\n\n\n
  • Supports dual boot (Linux + other OS).<\/li>\n\n\n\n
  • Configuration stored in \/etc\/lilo.conf<\/code>.<\/li>\n<\/ul>\n\n\n\n

    🔹 Limitation:<\/h3>\n\n\n\n
      \n
    • After changing configuration, you must run the lilo<\/code> command again.<\/li>\n\n\n\n
    • Does not understand filesystems (uses fixed disk locations).<\/li>\n\n\n\n
    • No interactive command interface.<\/li>\n<\/ul>\n\n\n\n

      👉 LILO is now mostly outdated.<\/p>\n\n\n\n

      \n\n\n\n

      2️⃣ GRUB<\/h1>\n\n\n\n

      GNU GRUB<\/strong> stands for GRand Unified Bootloader<\/strong>.<\/p>\n\n\n\n

      🔹 Features:<\/h3>\n\n\n\n
        \n
      • Modern and widely used Linux boot loader.<\/li>\n\n\n\n
      • Supports multiple operating systems.<\/li>\n\n\n\n
      • Has interactive command line interface.<\/li>\n\n\n\n
      • Automatically detects installed OS.<\/li>\n\n\n\n
      • Understands filesystems.<\/li>\n\n\n\n
      • Configuration file: \/boot\/grub\/grub.cfg<\/code>.<\/li>\n<\/ul>\n\n\n\n

        🔹 Advantages over LILO:<\/h3>\n\n\n\n
          \n
        • No need to reinstall after every change.<\/li>\n\n\n\n
        • More flexible and powerful.<\/li>\n\n\n\n
        • Supports network booting.<\/li>\n<\/ul>\n\n\n\n

          👉 GRUB replaced LILO in most modern Linux distributions.<\/p>\n\n\n\n

            \n
          • LILO<\/strong> is an older Linux boot loader used to load the Linux kernel.<\/li>\n\n\n\n
