You are troubleshooting a laptop running Windows 10. You need to restart the system using the diagnostic software on a DVD. You set the boot order in the UEFI BIOS to the internal DVD-RW drive. However, the laptop seems to ignore the diagnostic disk and boots directly into Windows. What action must you take to resolve the problem and boot from the DVD?
Configure the Secure boot settings - Secure Boot is a security standard developed by members of the PC industry to help make sure that a PC boots using only software that is trusted by the PC manufacturer. When the PC starts, the firmware checks the signature of each piece of boot software, including firmware drivers (Option ROMs) and the operating system. If the signatures are good, the PC boots, and the firmware gives control to the operating system. In this scenario, the laptop cannot boot using the diagnostic DVD because it does not have the required signature. Therefore, the system defaults to Windows.

You have a laser printer that has 2 separate paper trays. One of them is for standard paper and the other for legal paper. Whenever a user prints something for legal paper, the job does not seem to go through. The standard size paper is working fine. Which of the follow is most likely to be causing the problem?
The paper size for the tray is incorrect in the printer setup - The fact that the paper tray fits legal size paper would imply that legal size paper is supported by this printer. We are also still able to print jobs that use standard paper, so the queue is not causing the print jobs to get stuck. Many laser printers will require you to manually input the paper size for each tray. This is the easiest thing to check, and may likely be the solution.
A technician recently installed a new video card in a PC. The PC already has integrated video on the motherboard. When the technician turns on the PC, there is no video. Which of the following is most likely the cause?
The power connector for the video card is unplugged. - When a computer is powered up, it will immediately detect all video devices and then select the best one to use. Typically it will default to the video device where monitor is plugged in. In this case when the computer is turned on there are no beep codes to indicate something is wrong. Instead it behaves as if a monitor was unplugged. When you install a new card you will plug the monitor into the new card. If the new card does not have power then the motherboard will not detect it. If the motherboard does not detect it, it will treat the video as if there is only one option. It will select on board video and continue the boot process. The monitor will appear empty because it is plugged in to a video card that is not being used.
