3.Press the number that corresponds to the correct location for the installation of Windows you want to repair.
Typically this will be #1
4.Enter in the administrator password when requested
5.Enter in the following commands (X: is replaced by the actual drive letter that is assigned to the CD ROM drive.

COPY X:\i386\NTLDR C\:

COPY X:\i386\NTDETECT.COM C:\

6.Take out the CD ROM and type exit
