FC0-U71 Tech Concepts and Terminology Practice Question
A technician is setting up a new desktop computer and needs to install an operating system from a bootable USB flash drive. The computer powers on but boots directly into the existing hard drive instead of the USB drive. Which of the following should the technician configure to allow the computer to boot from the USB drive?
⚠ Common exam trap
Candidates often confuse operating-system tools like Device Manager or Disk Management with firmware settings that actually control the pre-boot device selection.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
BIOS/UEFI boot order
The firmware boot order controls which device the computer attempts to boot from first. If the internal hard drive precedes the USB drive, the system skips the USB media. Reordering the boot sequence in BIOS/UEFI so the USB drive is first allows the installation media to load as needed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
BIOS/UEFI boot order
Why this is correct
The boot order in BIOS/UEFI determines which device the firmware checks first for bootable media. If the hard drive is listed before the USB drive, the system will boot from the hard drive. Changing the boot order to prioritize the USB drive lets the technician boot the installation media as intended in this scenario.
- ✗
Windows Device Manager
Why it's wrong here
Device Manager runs inside a loaded operating system and manages hardware drivers and devices. It cannot influence which device the firmware selects during the pre-boot phase, so it cannot help the computer boot from a USB drive. This tool operates too late in the startup process to affect boot device selection.
- ✗
Task Scheduler
Why it's wrong here
Task Scheduler automates running programs or scripts within Windows based on triggers. It operates entirely within the running operating system and has no role in firmware-level boot device selection. It cannot cause the computer to boot from a USB drive, so it is irrelevant to this scenario.
- ✗
Disk Management console
Why it's wrong here
Disk Management is a Windows utility for partitioning, formatting, and assigning drive letters to storage devices after the OS has started. It has no control over firmware boot order and cannot make the computer boot from a USB drive. Using it would not resolve the boot sequence issue described.
