What is a limitation of LILO when used as a boot loader?

• A. It can import Windows boot options automatically.
• B. It supports multi-boot with other OS by default.
• C. It is not possible for all computers to tolerate modification of the MBR.
• D. It cannot be installed in the MBR.

Answer: (D)

The main idea here is how the boot loader sits in the system’s startup sequence. LILO operates as a two-stage boot loader that needs to be invoked by the BIOS, either from the MBR or a partition boot sector. On many machines, writing to the MBR is restricted or discouraged due to security policies, BIOS quirks, or disk configurations. Because of these limitations, using LILO as the primary boot loader in the MBR isn’t always possible or reliable, so its ability to serve as the sole boot manager is constrained. In other words, the need to avoid or restrict MBR installation on some systems is a real limitation of LILO, making it less flexible for straightforward multi-boot setups compared with more modern boot managers that reliably reside in the MBR and handle various OSes automatically.
