CompTIA A+ Core 2 (220-1202) — Question 177

After using a third-party disk optimization software package, a technician restarts a laptop and receives the message No operating system found. The technician verifies that the BIOS properly recognizes the SSD. Which of the following should the technician do next?

Answer options

• A. Update BitLocker settings in the BIOS.
• B. Replace the CMOS battery.
• C. Turn on from installation media and repair the MBR
• D. Isolate the system from the corporate network.

Correct answer: C

Explanation

The correct action is to boot from installation media and repair the MBR, as the disk optimization software may have affected the boot sector. Updating BitLocker settings or replacing the CMOS battery are not relevant to resolving an operating system detection issue. Isolating the system from the network does not address the underlying problem of the missing operating system.
