CompTIA A+ Core 2 (220-1002) — Question 348

A technician recently installed a new secondary hard drive in a Windows 10 desktop. After the installation, the computer displayed the following error message: No
Operating System Found. However, after unplugging the new hard drive, the error message no longer appeared. The technician then reconnected the new drive to continue troubleshooting.
Which of the following steps should the technician take NEXT?

Answer options

• A. Reboot into safe mode
• B. Check the boot order
• C. Format the drive
• D. Perform Windows Recovery
• E. Run the chkdsk command

Correct answer: B

Explanation

The correct answer is B, as checking the boot order is crucial to ensure that the system is trying to boot from the correct drive. If the new hard drive is set as the primary boot device without an OS, it will cause the error. The other options do not address the immediate issue of the boot sequence and may not resolve the error as effectively.
