Restore From Ldf Convert Backup File Generated From SQL Server To MDF And LDF Files?

Convert backup file generated from SQL server to MDF and LDF files? - restore from ldf

I drove a database using the Enterprise Admin and saved the backup disk wiz named MyBackup.bak "..
I would like to generate from this file, copy both files into MDF and LDF. Since you did not understand how to restore the "MyBackup.bak" again, I get an error "for the media database mydb 'set 2 family members, but are intended only 1st All members must pay" ..
If anyone can help me ... !
