My PC started crashing on boot up, I tried using rescue disk to restore boot files but now get ......
NTLDR missing ..press any key to restart

tried this as advised on forums.... using windows XP disc

copy e:\i386\ntldr c:\
copy e:\i386\ntdetect.com c:\
Once both of these files have been successfully copied, remove the CD from the computer and reboot.

NTLDR is missing

Also ensure you have Administrator privileges during any applicable elements of the process.

Files on Windows CD are compressed, so you have to use "expand" command, not "copy"

expand e:\i386\ntldr.ex_ c:\
expand e:\i386\ntdetect.co_ c:\

The two files mentioned are not compressed. Those files help in setting up a system structure to load/copy.

True. Just checked. My bad
