Restore msdb file

I had a problem with operating system so copy copied all of my database
backup files to another. I reinstalled the operating system and restored all
of the except the msdb database.
I received the following error when trying to restore msdb database.
The file () cannot be overwritten. It is being used by database msdb use
WITH MOVE to identify a valid location for the file.
Please help me resolve this issue.Use the MOVE option of the RESTORE command. Documented in Books Online. Start by investigating the
file layout of your backup using RESTORE HEADERONLY and RESTORE FILELISTONLY.
