A server is rebooted after maintenance. Upon reboot, the video display reports it cannot find the boot loader. Which of the following should the administrator check FIRST?

Question

Options

• AThe server has a power surge
• BThe BIOS boot sequence is incorrect
• CThe server is overheating
• DThe boot loader is incompatible with the server

• B
  90% (26)
• C
  3% (1)
• D
  7% (2)

Explanation

When a server cannot find the boot loader immediately after maintenance, the most likely and most easily corrected cause is that the BIOS/UEFI boot order was inadvertently changed during maintenance. For example, if a USB drive or optical disc was connected during maintenance, the BIOS may now be attempting to boot from that device instead of the primary hard drive containing the OS and boot loader. This is a common, non-destructive misconfiguration that is quick to verify and fix. The principle of 'check FIRST' points to the simplest, most probable cause. A power surge would likely cause more widespread hardware symptoms. Overheating would not produce a 'boot loader not found' message. Boot loader incompatibility would not suddenly appear after routine maintenance unless the boot sector was directly modified.
