    The command seems incorrect. Try another command:

    New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\stornvme\Parameters\Device" -Name "ForcedPhysicalSectorSizeInBytes" -PropertyType MultiString -Force -Value "* 4095"

    To get the value:

    Get-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\stornvme\Parameters\Device" -Name "ForcedPhysicalSectorSizeInBytes"

    The error

    Wait on the Database Engine recovery handle failed

    means the SQL Server Database Engine service did not start during setup. The PowerShell registry step from the Stack Overflow thread is only one possible workaround (for the 4‑KB sector size issue on some Windows 11 disks). If that PowerShell command “does not recognize” the file path, the path being used is incorrect for the actual SQL Server instance and version on the machine.

    Use these steps instead of relying on that single PowerShell line:

    1. Locate the SQL Server error log actually created by the failed setup
      • On Windows 11, for a default instance, the log is typically under one of these paths (depending on version):
        • C:\Program Files\Microsoft SQL Server\MSSQL15.MSSQLSERVER\MSSQL\LOG\ERRORLOG (SQL Server 2019)
        • C:\Program Files\Microsoft SQL Server\MSSQL16.MSSQLSERVER\MSSQL\LOG\ERRORLOG (SQL Server 2022)
        • For Express, the instance folder name will be different (for example MSSQL15.SQLEXPRESS), and the log is in ...\MSSQL\LOG\ERRORLOG.
      • If setup created a named instance, replace MSSQL15.MSSQLSERVER with the actual instance folder name shown under C:\Program Files\Microsoft SQL Server\.
    2. Open the ERRORLOG file and check for the specific cause
      • If the log contains a line similar to: There have been 256 misaligned log IOs which required falling back to synchronous IO. then the failure is due to the known Windows 11 disk sector size issue. In that case, follow the workarounds in the Microsoft article about “Troubleshoot SQL Server errors related to system disk sector size greater than 4 KB” (Scenario 3 and Scenario 4) instead of the Stack Overflow PowerShell snippet.
      • If there is no “256 misaligned log IOs” message, the failure is caused by something else (for example, upgrade script failures, missing installer cache files, or other startup errors). In that case, the PowerShell registry workaround is not applicable and will not fix the problem.
    3. If the error appears during a CU/SP or upgrade
      • When applying a cumulative update or service pack, the same message can appear if the T‑SQL upgrade scripts fail. In that case, the SQL Server error log will show errors 912 and 3417 and messages about script upgrade failures. The resolution is to troubleshoot the script failure as described in the “Troubleshoot common SQL Server Cumulative Update installation issues” article, not to modify registry paths.
    4. If setup itself is corrupted or missing files
      • If the log shows setup/installer issues rather than engine startup problems, use the standard setup repair steps:
        • Download the SQL Server media again and rerun setup from the fresh image.
        • If installing over the network, copy the media locally and run from a local folder.
        • If Windows Installer cache files are missing, repair the installation or restore the missing MSI/MSP files using the methods described in the “Setup errors caused by missing installer files in Windows cache” section (repair, FixMissingMSI tool, scripts, or restore from backup).
    5. About the PowerShell path problem
      • The PowerShell command from the Stack Overflow answer typically references a specific instance path under HKLM:\SYSTEM\CurrentControlSet\Services\MSSQL$<InstanceName> or similar. If Windows 11 “does not recognize” the file path, it usually means:
        • The instance name in the path does not match the one created by setup.
        • The version-specific folder (for example MSSQL15.MSSQLSERVER vs MSSQL16.MSSQLSERVER or MSSQL17.MSSQLSERVER) is wrong for the version being installed.
      • Correct the instance name and version in the path to match the actual folders and registry keys on the machine, or skip that workaround entirely if the error log does not show the 4‑KB sector/misaligned IO problem.

    In summary, the next step is to open the SQL Server ERRORLOG in the correct instance folder and look for either the “256 misaligned log IOs” message or other startup errors. Apply the sector‑size workaround only if that specific misaligned IO message is present; otherwise, troubleshoot based on the actual error messages in the log or repair/re‑download setup if installer files are missing.
