CompTIA A+ Core 2 (220-1002) — Question 345

Ann, a user, calls a technician and reports that her PC will not boot. The technician confirms the memory, power supply, and monitor are all working. The technician runs internal diagnostics on the PC, but the hard drive is not recognized.
Which of the following messages will be displayed?

Answer options

Correct answer: B

Explanation

The correct answer is B, 'No boot device available', because the system cannot locate the hard drive to boot from it. Option A, 'NTLDR not found', would be relevant if the hard drive was recognized but missing the boot loader. Option C, 'Operating system not found', applies when a bootable device is recognized but lacks an OS, and D, 'BIOS ROM checksum error', indicates a BIOS-related issue rather than a boot device problem.
