CompTIA A+ Core 1 (220-1101) — Question 237

A user tries to turn on a computer but gets the following error message: Bootable device not found. The computer had no issues yesterday. Which of the following is the most likely reason for this error?

Answer options

• A. The HDD is malfunctioning.
• B. The mouse and keyboard are not connected.
• C. A misconfigured boot device is in the BIOS
• D. The network cable is unplugged.

Correct answer: A

Explanation

The most likely reason for the 'Bootable device not found' error is that the HDD is malfunctioning, preventing the system from detecting the boot device. The other options, such as disconnected peripherals or an unplugged network cable, do not affect the system's ability to boot from the hard drive.
