The screen of a previously working computer repeatedly displays an OS Not Found error message when the computer is started. Only a USB drive, a keyboard, and a mouse are plugged into the computer. Which of the following should a technician do first?
Show Answer & Explanation
Correct Answer: C. Check boot options.
A USB drive is connected, which may be set as the first boot device, causing the OS Not Found error. Checking boot order is the fastest and least destructive first step. Running recovery tools or repartitioning before verifying boot order could cause unnecessary damage. Switching from UEFI to BIOS is drastic and not indicated yet. Always eliminate simple causes first.
