Difficulty: MediumOS Installation and Upgrade Methods

An IT support technician is tasked with performing an in-place upgrade of a workstation from Windows 10 Pro to Windows 11 Pro. During the pre-upgrade assessment, the technician notes that the target system's storage drive uses the Master Boot Record (MBR) partition scheme and the system boots using Legacy BIOS mode. Which of the following actions must the technician complete first to meet Windows 11 installation prerequisites?

  1. Convert the disk partition scheme from MBR to GPT using mbr2gpt.exe and configure the system firmware to boot using UEFI mode.Answer
  2. B
    Run the Windows 11 installation media directly, as the setup wizard automatically converts MBR disks to GPT during an in-place upgrade.
  3. C
    Perform an edition upgrade to Windows 10 Enterprise, which bypasses the UEFI requirement for Windows 11 upgrades.
  4. D
    Execute sfc /scannow /convertgpt from an elevated command prompt to convert the drive scheme while keeping Legacy BIOS active.

Answer

Convert the disk partition scheme from MBR to GPT using mbr2gpt.exe and configure the system firmware to boot using UEFI mode.
Windows 11 mandates UEFI firmware and a GUID Partition Table (GPT) disk layout. Converting the partition table using mbr2gpt.exe and enabling UEFI mode in firmware enables the machine to meet installation requirements for an in-place upgrade.

Step-by-Step Solution

1
Identify Windows 11 hardware and firmware prerequisites.
Recognize that Windows 11 strictly requires UEFI firmware mode and a GPT (GUID Partition Table) partition style.
Systems using Legacy BIOS and MBR partition tables will fail the mandatory Windows 11 compatibility check.
2
Convert the existing drive without data loss.
Use the Windows built-in utility mbr2gpt.exe to convert the disk layout from MBR to GPT.
This tool preserves existing operating system data and system files while restructuring the partition table.
3
Reconfigure motherboard firmware.
Change the system boot mode from Legacy BIOS to UEFI in the system firmware/BIOS setup.
Changing the disk to GPT requires UEFI boot mode to initialize the operating system successfully.
