How to remove Ubuntu

How to remove Ubuntu from dual boot pc.  I am giving my old pc to my 12 yr old grandson.  He is in special ed with a learning disability.  He has learned to logon to XP but gets confused with Ubuntu.  Windows XP is currently on the C Drive, Ubuntu is installed on the D drive.  How do I remove Ubuntu 8.04 from the D drive?I am an old (76 yr old) unix user, having used unix on an old Compac System Pro and Sun Sparc 2000 running Oracle and Microfocus Cobol.  But this time I need some help restoring the pc so my grandson can use it.  Respectfull to all.
