I have had the same problem. I was gone and my sis was using my pc and it froze. When I rebooted it once I returned I received the same msg..."NTLDR is Missing". My problem is it would not reboot in Win XP Pro, it would not allow me to run a system recovery, it would not allow me to reinstall. I have had to put Windows 98 SE back on. It won't even allow me to upgrade to Windows XP Pro. How do you recover that file or can you? Any suggestions would help.
