SQL Server service cannot start (case)

SQL Server service cannot start

1) When you start the SQL Server (SQLEXPRESS) service, you are prompted with the following error:
The local computer cannot start the SQL Server (SQLEXPRESS) service
Error 3: The system cannot find the path specified
I found some information on the internet, but I couldn't solve the problem.

Workaround: 1 first go to the service to find SQL Server (SQLEXPRESS), look at its properties, copy the path of the executable file 2. Go to the registry to find Hkey_local_machine/system/controlset001/services/mssql$sqlexpress (because my 2005 is a named instance, you find a name similar to that), After finding this, there is a imagepath that changes its data value to the path of the executable file that was originally copied.
