打开SSMS工具，先断开连接，再新建查询，执行以下命名还原
USE master
GO
RESTORE DATABASE master
FROM disk='C:\Program Files\Microsoft SQL Server\MSSQL.1 \MSSQL\Backup\master.bak'
GO

数据库中的显示的消息应为：
已为数据库 'master'，文件 'master' (位于文件 1 上)处理了 376 页。
已为数据库 'master'，文件 'mastlog' (位于文件 1 上)处理了 6 页。
已成功地还原了 master 数据库。正在关闭 SQL Server。
SQL Server 正在终止此进程。
则表示master数据库还原成功,启动服务后进入SSMS即可看到master数据库了。
