CREATE DATABASE permission denied in database 'master'. unable to get the permission

I am making a database in sql server and it shows an error that "CREATE DATABASE permission denied in database 'master'"
I am using the administrator log in itself.
What i need to do?
Please suggest a fix!

The user must be a member of dbcreator server role for user to have enough permissions to create a database.

You can execute the following statement to make a user member of dbcreator server role.

EXEC master..sp_addsrvrolemember @loginame = N'Shubhankar', @rolename = N'dbcreator'
GO

Or you Can/Should use

ALTER SERVER ROLE  [dbcreator]  ADD MEMBER [Shubhankar];
GO

Members of sysadmin role are by default members of dbcreator server role therefore they can create databases too.
