how to get xp password?

Hi all,

I need your help, my brother has got a problem with his computer as windows xp would not start up due to boots that will not boot up or the files could be corrupted. I can't be able to do the fixboots or chkdsk because he cant remember the password for the administrator. And I can't log on into the safe mode as it will not boot up.


Does anyone know how i can recover to get the administrator password using hiren boot cd if that is possible?
