## Answers

### Answer by UTKARSHA SINGHROUL

Boot Loader is a small program that loads the Operating System into the Computer Memory when the system is booted and also starts the Operating System. Boot Loader is also known as **Boot Manager or Bootstrap Loader.** It is usually the first software to run after power-up or re-start. A Boot Loader mainly manages and executes the Boot sequence of a computer system. When a computer system is power up or restarted, the **Basic Input and Output System (BIOS)** performs many initial tests and then transfer control to the main Boot Loader. A Boot Loader is associated with only one or a specific Operating System at a time. It may be possible that a computer system is equipped with two different Operating System. So in this condition, either one or another will load, depending on the user preference or what has been pre-programmed to start automatically. If a computer is to be used with LINUX, a special Boot Loader installation is required. The most common Boot Loader is known as **Linux Loader (LILO)** and **LOAD Linux (LOADLIN)**. LILO is the most popular Boot Loader among LINUX users. With **RED HAT LINUX**, another Boot Loader i.e., **GRand Unified Bootloader (GRUB)** is used. \
