Which boot loader enables booting of multiple operating systems on a Linux system?

• A. Bios
• B. Master Boot Record
• C. Ntldr
• D. LILO/GRUB

Answer: (D)

The concept here is how a boot loader can present a menu to start any installed operating system and load the chosen one. LILO and GRUB are designed to manage multi-boot configurations on a Linux system. They read their configuration, detect installed systems, and present a boot menu so you can pick Linux, Windows, or another OS at startup. They then load the selected kernel or chainload the other OS accordingly. The BIOS is just the firmware that starts the boot process and hands control to the boot device; it isn’t a multi-boot manager. The Master Boot Record holds the initial boot code but isn’t itself the tool that lets you choose between multiple OSes. Ntldr is the Windows NT/XP boot loader, not a Linux multi-boot manager. So the boot loader that enables booting of multiple operating systems on a Linux system is LILO/GRUB.
