My OS is Windows ME and it has been working well for the past year. All of a sudden, when I booted my PC yesterday an "NTLDR is missing press any key to restart" message appeared and when I press any key, it just loops all over again. When I reboot, the same thing occurs. I notice that lately another message "time and date not set" appears also and thats because of the lithium battery. How do i fix this problem? Does the lithium battery have anything to do with "NTLDR is missing" message? Thanks in advance!
