When attempting to start Windows, you may receive an error message saying that NTLDR is not found or missing and you are asked to press any key to restart.
This issue may occur if your start device (such as a floppy disk drive, hard disk drive, or CD-ROM drive) does not contain boot files.
To resolve this issue, remove the non-system disk from your boot device. For example, remove the non-system disk from the floppy drive or the CD-ROM drive.
Change your computer's boot sequence. Make sure that your computer's first boot sequence is the CD-ROM Drive.
Boot Windows and start the Recovery Console
