Hi @HARI DUDANI
Thanks for your question.
The "Could not find the database engine startup handle" error is a generic error message indicating that SQL Server failed to start during configuration. There are various potential causes for this issue.
To determine the cause of SQL Server not starting, you can check the SQL Server error log located at C:\Program Files\Microsoft SQL Server\MSSQL15.MSSQLSERVER\MSSQL\ERRORLOG (assuming a default installation). This log file provides valuable information about the startup process and any encountered errors.
Please share the error information from the error log.
If you find an error message about 256 misaligned reads, this is a known issue andbelow article suggests workarounds.
Thank you!
