Now ,I was planning to use it to format my PC since I dont have XP cd
When you don't have the Xp cd, then you have a problem, indeed.
But you told that the mechanic have in the past installed a program that you can use in the future for quick format the drive.
From my opinion can you still use that program.
I don't know, why you said, it is history.
I can tell you, you must do this and this, but with that you don't come far.
I think that it is smart from you, that you ask at a good friend or he\she has still Windows Xp install cd., if not than is there only the possibility that you buy a new o.s.
