If I understand the question correctly,  think you simply have to put the DB into single user mode prior to restoring from the backup.  To do this, you can follow the instructions here:

Because you can't Restore a database when it's on use you need to set the database in single-user mode so no one else can connect but you. The problem with master database is that it's a system database so you need to set the MSSQL instance in single-user mode instead of the database.

My question is why do you need to perform a restore master database?
