Win10 Pro current build
2TB HDD - WD20EZRZ-002Z5HB0

I am trying to move to Windows 11 from Windows 10
When I perform MBR2GPT /Validate I get the following error: Disk Layout validation failed for disk

Sector size is 512 bytes

I completed a Chkdsk on both system reserved and system partitions and fixed all issues. Runs clean.

What is nature of issue and how do I fix

    First scannow:

    Windows Resource Protection found corrupt files and successfully repaired them.

    Second scannow:

    Windows Resource Protection did not find any integrity violations.

    Open administrative command prompt and type or copy and paste:

    reagentc /info
    reagentc /disable
    diskpart
    sel dis 0
    det dis
    lis par
    sel par 4
    det par
    del par override
    lis par
    exit
    reagentc /enable
    reagentc /info

    Type:
    ctrl + a
    ctrl + c

    Paste the above commands with results into this thread typing: ctrl + v

    Reboot the computer and run mbr2gpt /validate

    Post images of the command with results.

    If validated then continue with the conversion: mbr2gpt /convert /allowfullos

    If the conversion is successful then boot using UEFI.

    In case there are any problems post a new disk management and new log file results (tuneup, diskpar, mbr2gpt)
