NTLDR is Missing in XP how to solve

Set the BIOS to boot CD before Hard Disk. Boot the XP CD and, instead of
Setup, take the immediate R for Repair. Assume any password requested is
blank, and TAB over. Assuming this sees the CD as D (likely) give:

COPY D:\i386\ntldr C:\
COPY D:\i386\ntdetect C:\
(Hear "C:" is the system drive and "D:" is the CD drive)
(a file that may also be missing)
then rebuild the boot configuration boot.ini file by
Attrib -H -R -S C:\boot.ini
(if not found skip the next line)
DEL C:\boot.ini
BootCfg /Rebuild
