220-1102 Operating Systems Practice Question
A technician installs a second SSD with a new copy of Windows 10 on a computer that already has Windows 10 on the primary drive. After installation, the computer boots directly to the new drive, bypassing the boot menu. The technician wants to configure the system to display a boot menu allowing selection between the two Windows installations. Which command-line tool should the technician use to modify the boot configuration?
⚠ Common exam trap
Test-takers frequently confuse msconfig's 'Boot' tab with the ability to fully manage multi-boot configurations, not realizing that msconfig only modifies the current boot entry's options and cannot add or remove boot entries or change the boot manager's policy.
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
✓
bcdedit
The bcdedit command-line tool is used to manage Boot Configuration Data (BCD) on Windows systems. It allows the technician to modify boot entries, set the boot menu policy, and configure the boot manager to display a selection menu between multiple Windows installations. In this scenario, bcdedit can be used to enable the boot menu and set the appropriate timeout value.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
bcdedit
Why this is correct
bcdedit is the definitive command-line tool for managing the Boot Configuration Data (BCD) store on Windows 10. It enables precise control over boot options, including the ability to add new boot entries for an additional operating system, specify the display order in the boot menu, and configure the timeout interval. Unlike GUI tools, bcdedit can create, delete, and modify entries at a granular level, making it the correct choice for a technician setting up a dual-boot scenario with a second SSD.
- ✗
msconfig
Why it's wrong here
msconfig, the System Configuration utility, provides a simplified graphical interface for basic boot settings such as the default OS and boot timeout, and it can toggle safe boot options. However, its capabilities are limited to modifying existing entries; it cannot create new boot entries or fully manage the BCD store. While it can adjust how the boot menu behaves, it lacks the depth and control required to properly integrate a freshly installed second Windows 10 SSD into the boot manager, making it inadequate for this task.
- ✗
Diskpart
Why it's wrong here
Diskpart is a disk partitioning and management tool used to create, delete, format, and assign drive letters to disk volumes. It operates at the storage layer, dealing with partitions and file systems, not the boot configuration. The BCD store, which contains the boot menu entries, is a separate database located on the system partition, and Diskpart has no mechanism to read or modify it. Therefore, while Diskpart could have been used to prepare the second SSD, it cannot add or manage Windows boot entries.
- ✗
Bootrec
Why it's wrong here
Bootrec (bootrec.exe) is a recovery tool primarily designed to repair the boot sector, rebuild the BCD, or fix master boot record issues. When run with the /RebuildBcd switch, it scans all drives for Windows installations and reconstructs a new BCD store, but this process is indiscriminate and does not allow fine-grained control over individual entries like timeout or display order. It is a repair utility, not a management utility, so it may restore a functional boot menu but cannot natively add a custom entry for a new Windows installation while preserving existing customization.
