How to Upgrade Windows 10 to Windows 11

Overview

This guide covers the steps required to upgrade an older Windows 10 system running MBR partition layout and legacy BIOS to Windows 11 using GPT partition layout and UEFI framework. This change is necessary as Windows 11 requires modern partition and BIOS settings.

Key Steps for Upgrade

Preparation

  1. Check Partition Style and BIOS Mode:

    • Use Disk Management to verify the partition style (MBR).
    • Confirm BIOS mode using the System Information tool (Legacy BIOS).
  2. Create Backup:

    • Prior to any system changes, create a full backup of your computer to prevent data loss.
  3. Subscribe and Support:

    • Subscribe to the channel and like the video for further tutorials.

Conversion Process

  1. Convert MBR to GPT:

    • Open settings → Update & Security → Recovery → Restart for Advanced Startup.
    • Open Command Prompt from Advanced Options.
    • Validate the drive for conversion using mbr2gpt /validate.
    • Convert the drive using mbr2gpt /convert.
  2. Switch BIOS to UEFI:

    • Change the boot mode from Legacy BIOS to UEFI in your computer's firmware settings.
    • Enable TPM 2.0; TPM settings may vary by motherboard (e.g., Intel PTT or AMD FTPM).
  3. Confirm Changes:

    • Use System Information and Security Processor Details to confirm TPM and UEFI mode.
    • Use Disk Management to confirm partition style change to GPT.

Upgrade Process

  1. Windows Update:

    • Check for official update notification in Settings → Update & Security → Windows Update.
  2. Installation Assistant Tool:

    • If upgrade notification is not available, download Windows 11 Installation Assistant from Microsoft’s website and run it as an administrator.
  3. Finalize Installation:

    • Accept and install through the assistant tool and restart the computer.
  4. Post-Installation:

    • Perform final checks for updates and patches.

Troubleshooting and Considerations

  • Primary Partitions: Ensure only three primary partitions are on the drive before conversion.
  • Potential Issues: Attempt a clean installation if long-standing Windows 10 installations cause upgrade issues.
  • Comments & Feedback: Encourage viewers to engage through comments and subscriptions.

Closing Remarks

Utilize these instructions to upgrade effectively and minimize potential upgrade issues, always ensuring backup creation as a precautionary measure.
