The password file you have created has the wrong name. Read the section "Creating and Maintaining a Password File" in the Administrator's Guide. It will tell you how to create the password, and how to connect as SYS when you have created it.

What did you discover when you googled "ora-12638"?

BTW, the syntax is 'sqlplus / as sysdba'. Note the space between "/" and "as".

ORA-12638: Credential retrieval failed
 *Cause:  The authentication service failed to retrieve the credentials of a
          user.
 *Action: Enable tracing to determine the exact error.

You don't need to post an image to post a text, just post the text, inline and formatted.

Ok let's explain:
"My old instance has failed to work" what this mean? What is an instance for you? what does mean "failed to work"? Note this is not an Oracle error message.

"so i cannot login as sysdba anymore", what does mean "cannot login"? An error? Which one? show us, use SQL*Plus and copy and paste your session.

"it gives an error" and you think that not sharing this error with us will help us in any way to help you?

If you lost the key to your house, would you decide the solution is to build a new house?

Instead of worrying about creating a new database, why not deal with what should be the rather simple problem of getting logged on to your existing database? Even if this is just a personal test database you have to ask yourself what you would do if it were the company's number one, customer facing, revenue generating, production database.

And to help you with the problem of getting logged in to your existing database, we need actual commands and actual error messages, not your vague descriptions of them.

What do you mean by "instance" and "database"?

In that case, you need to use the oradim utility to create the new windows service; use notepad to create a new parameter file, with the db_name set to the name of the database; set your ORACLE_SID environment variable to the name of the new instance; connect as sysdba; and startup.
