CompTIA A+ Core 2 (220-1002) — Question 261

A customer has been using a computer to download and copy files to a USB flash drive. The customer accidentally stepped on the power strip, and the computer suddenly powered off. When the computer turned back on, it displayed an error message: No OS found. Which of the following should a technician perform
NEXT?

Answer options

• A. Connect a UPS.
• B. Repair the OS.
• C. Check the boot order.
• D. Run hardware diagnostics.

Correct answer: C

Explanation

The correct action is to check the boot order because the unexpected shutdown could have altered the system's ability to find the operating system. Repairing the OS may not be necessary if the boot order is misconfigured, and connecting a UPS or running hardware diagnostics won't address a boot order issue directly.
