FIXMBR is a repair tool used to repair which of the following?

• A. BIOS
• B. Master Boot Record
• C. Boot Sector
• D. Partition Table

Answer: (B)

Fixing the Master Boot Record is about the tiny boot code at the very start of the hard disk. The MBR is the 512-byte sector that begins the boot process and typically also contains the partition table. If that boot code is corrupted or overwritten by malware, the computer may fail to boot. FixMBR replaces that boot code with a clean, working version so the system can correctly locate and hand off control to the boot sector of the active partition, allowing the operating system to start. The BIOS is separate firmware on the motherboard and isn’t modified by this tool. The boot sector (or volume boot record) is the first sector of the active partition that actually loads the OS after the MBR passes control; FixMBR doesn’t repair that sector directly, it fixes the code that starts the chain of boot loading. The partition table describes partitions and lives in the MBR, but fixing the MBR’s boot code is what FixMBR does, not repairing the partition table itself.
