一朋友在升级SQL Server 2014后， SQL Server启动不了，寻求我的帮助。检查SQL Server 2014的错误日志，具体错误信息如下：

This is a serious error condition which might interfere with regular operation and the database will be taken offline. If the error happened during upgrade of the 'master' database, it will prevent the entire SQL Server instance from starting. Examine the previous errorlog entries for errors, take the appropriate corrective actions and re-start the database so that the script upgrade steps run to completion.
