How to Boot Up if NTLDR Is Missing

By Bobson St. Pierre

Microsoft's NT Loader (NTLDR) was first introduced with the release of Windows NT and served as the systems boot loader until the Windows XP operating system. It functions as a boot loader for Windows. The file usually is run from the local root drive of the system and is aided by two other files, boot.ini and If any of those three files are deleted or damaged, the system may not boot up. You must place those files back on your hard drive in order to boot up.
