What is LILO?

A specific bootloader must be installed on a computer before it can be used with Linux. The Linux Loader, or LILO, is essentially the most popular Linux bootloader that loads Linux into memory and launches the operating system. It can execute a number of tasks as either a master boot program or a secondary boot program, including finding the kernel, identifying other supporting programs, loading memory, and running the kernel. However, it is important to note that there exist several other bootloaders apart from LILO, with two of them being LOADLIN (LOAD LINux) and GRUB (GRand Unified Bootloader).
