Zorluk: Çok zorOS Installation and Upgrade Methods

A desktop support technician is tasked with upgrading an existing workstation running 64-bit Windows 10 Pro to Windows 11 Pro. The system currently uses Legacy BIOS boot mode with a Master Boot Record (MBR) disk layout. To meet Windows 11 system requirements, the technician must convert the system disk to GUID Partition Table (GPT) and enable UEFI mode with Secure Boot before performing an in-place upgrade, all while preserving user files and applications. Place the required steps in the correct sequential order from first to last.

  1. 1Execute `mbr2gpt /validate /allowFullOS` from an elevated command prompt.
  2. 2Execute `mbr2gpt /convert /allowFullOS` from an elevated command prompt.
  3. 3Restart the system into firmware configuration, disable CSM (Legacy BIOS mode), and enable UEFI Boot with Secure Boot.
  4. 4Boot into Windows 10 and launch the Windows 11 installation setup media to perform the in-place OS upgrade.

Cevap

The correct sequence begins with validating the disk layout using `mbr2gpt /validate`, followed by executing the disk conversion with `mbr2gpt /convert`, updating system firmware from Legacy BIOS to UEFI with Secure Boot enabled, and finally executing the Windows 11 installation setup to complete the in-place upgrade.
The disk must first be validated using `mbr2gpt /validate /allowFullOS` to verify layout compliance. Next, `mbr2gpt /convert /allowFullOS` changes the partition table from MBR to GPT. Immediately after conversion, the system must be rebooted into firmware to switch from Legacy BIOS/CSM mode to native UEFI with Secure Boot. Finally, with UEFI mode active and GPT established, the technician boots Windows and launches Windows 11 setup to perform the in-place upgrade.

Adım Adım Çözüm

1
Run validation tool in Windows
The `mbr2gpt /validate /allowFullOS` command checks the disk layout and confirms system eligibility without modifying data.
Validation prevents failed conversion attempts that could corrupt partition structures.
2
Convert partition table to GPT
The `mbr2gpt /convert /allowFullOS` command reconfigures the partition structure to GPT and creates the required EFI System Partition.
Windows 11 mandates a GPT disk layout to boot under UEFI mode.
3
Reconfigure system firmware
Restarting into system setup, turning off Compatibility Support Module (CSM)/Legacy mode, and turning on UEFI Boot and Secure Boot aligns hardware settings with the new disk partition layout.
The converted disk can no longer boot under Legacy BIOS mode; it requires UEFI mode.
4
Run Windows 11 Setup
Launching the Windows 11 installer allows the system to verify TPM 2.0, Secure Boot, and UEFI requirements, completing the in-place upgrade.
The OS upgrade can only proceed once all hardware and partition prerequisites are satisfied.
