220-1102 Operating Systems Practice Question
A user needs to modify the boot order on a Windows 10 computer to boot from a USB drive. Which tool should the user access during the boot process?
⚠ Common exam trap
Test-takers frequently confuse Device Manager, which is a familiar Windows tool for managing hardware, with the firmware-level BIOS/UEFI interface that actually controls boot order, leading them to incorrectly select Device Manager.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
BIOS/UEFI firmware settings
To change the boot order on a Windows 10 computer, you must access the BIOS/UEFI firmware settings during the boot process (typically by pressing a key like F2, F12, Del, or Esc). This firmware interface controls the sequence of boot devices, allowing you to prioritize a USB drive over the internal hard drive. Device Manager is an operating system tool used to manage hardware drivers and devices after Windows has loaded, not for altering boot order.
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 firmware settings
Why this is correct
The boot order is stored in non-volatile firmware (NVRAM) on the motherboard. Accessing the UEFI/BIOS setup utility during POST—typically by pressing Del, F2, F10, or Esc—allows you to reorder the boot sequence so the system checks the desired device (e.g., USB, optical drive, or network) before the internal hard drive. This setting precedes the operating system and is independent of any Windows control panel or command-line utility.
- ✗
Device Manager
Why it's wrong here
Device Manager is a Windows MMC snap-in (devmgmt.msc) that provides a centralized view of the system's hardware resources, including installed drivers, IRQ assignments, and device status. It enables enabling, disabling, updating, or rolling back drivers, but it has no influence over the firmware-level boot sequence. The boot order is determined by the motherboard's NVRAM before Windows loads, so Device Manager cannot access or modify that data.
- ✗
Task Manager
Why it's wrong here
Task Manager (taskmgr.exe) gives real-time visibility into running processes, CPU/memory/disk utilization, startup applications (in Windows 10 via the Startup tab), and user sessions. Its Startup tab controls which programs launch after Windows boots, not the pre-boot device priority. Because the boot order is selected by the firmware before the OS starts, Task Manager—a user-mode OS tool—cannot alter which disk or USB drive is read first.
- ✗
System Configuration (msconfig)
Why it's wrong here
System Configuration (msconfig.exe) is a diagnostic utility that toggles boot modes (Safe Boot, minimal logging), enables or disables services and startup items, and sets boot timeout or debugging parameters in the Windows Boot Configuration Data (BCD). These changes affect Windows boot behavior after the BIOS initiates the selected device, not the firmware's device search order. Thus msconfig can specify which OS installation or recovery environment to start, but it cannot decide whether the computer attempts USB before hard drive during POST.
