Question 1 of 334
A technician needs to run a diagnostic DVD on a laptop running Windows 8.1. After setting the boot order in the UEFI BIOS to the internal DVD-RW drive, the laptop still boots into Windows. Which of the following settings needs to be adjusted in order for the laptop to boot from the DVD-RW drive?
    Correct Answer: C

    The setting that needs to be adjusted is Secure Boot. Secure Boot is a feature in UEFI BIOS that ensures only trusted software can be loaded during the boot process. Since the diagnostic DVD is not signed in a way that Secure Boot recognizes, it prevents the laptop from booting from the DVD-RW drive. Disabling Secure Boot will allow the laptop to boot from the DVD-RW drive, as it will no longer restrict the boot process to trusted software only.
