LPIC-1 System Architecture Practice Question
What is stored in the first sector of a hard disk (Master Boot Record)?
⚠ Common exam trap
It's easy for candidates to confuse the MBR with the entire boot process, mistakenly thinking the kernel or root filesystem is directly stored in the first sector, when in reality the MBR only contains minimal boot code and partition metadata.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Master Boot Record (boot loader and partition table)
The Master Boot Record (MBR) occupies the first sector (sector 0, 512 bytes) of a hard disk and contains both the boot loader code (first 446 bytes) and the partition table (next 64 bytes), plus a 2-byte signature (0x55AA). This structure is essential for BIOS-based booting, as the BIOS loads the MBR into memory and executes the boot loader, which then uses the partition table to locate the active partition and load the operating system.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The Master Boot Record (boot loader and partition table)
Why this is correct
The MBR contains boot loader code and partition table.
- ✗
The partition table only
Why it's wrong here
The MBR contains both boot code and partition table.
- ✗
The Linux kernel
Why it's wrong here
The kernel is loaded from a file on a filesystem, not stored in MBR.
- ✗
The root filesystem
Why it's wrong here
Root filesystem is stored in a partition, not the MBR.
