    The gist of this error message is that SQL Server did not start when Setup wanted to run post-configuration. There can be multiple reasons for this. The by far most common reason is a known issue where Windows reports a disk sector size that SQL Server is not able to cope with. To verify that you are victim to this problem, you should look in the SQL Server error log which you find in C:\Program Files\Microsoft SQL Server\MSSQL16.SQLEXRESS\MSSQL\LOG\ERRORLOG and look for a message that talks about 256 misaligned reads.

    Microsoft has published the article Troubleshoot SQL Server errors related to system disk sector size greater than 4 KB which discusses workarounds for this problem. Basically, you need to make the registry edit described in the article. Very important! You need to reboot Windows for the change to take effect.

    If you don't find the message about 256 misaligned reads, please upload the ERRORLOG so that we can take a look. (You will need to rename it to ERRORLOG.txt for the forum software to accept it.)

    The error "Wait on the Database Engine recovery handle failed" on Windows 11 is usually caused by a disk sector‑size issue or another startup failure of the Database Engine during setup.

    Follow these steps to troubleshoot on Windows 11:

    1. Check the SQL Server error log
      • Go to the path shown in the installer (for example): C:\Program Files\Microsoft SQL Server\MSSQL16.MSSQLSERVER\MSSQL\LOG\ERRORLOG
      • Open ERRORLOG and look for messages around the time of setup, especially:
        • "There have been 256 misaligned log IOs" or
        • "Cannot use file ... because it was originally formatted with sector size 4096 and is now on a volume with sector size 16384".
    2. If the log shows misaligned IO or sector‑size errors
      • This is a known Windows 11 + storage issue where the reported physical sector size is greater than 4096 bytes and SQL Server cannot start.
      • Use the guidance in the disk sector size troubleshooting article to apply the appropriate workaround (for example, adjusting storage driver settings or using a volume with 4‑KB sector size) and then rerun SQL Server setup.
    3. If the log does not show sector‑size errors
      • The message is still a generic indicator that the Database Engine could not start. In that case, use the error details in ERRORLOG (other messages near the failure) to identify the specific cause and fix it, then rerun setup.

    On Windows 11, the sector‑size issue is one of the most common causes of this exact error during SQL Server Express installation, so checking the error log for those messages is the key first step.
