NTLDR (NT Loader) on buudilaadur kõikide Microsoft's Windows NT operatsiooni süsteemides samuti ka Windows XP ja Windows Server 2003. NTLDR käivitub tavaliselt primaarselt kõvakettalt, kuid ta võib käivituda ka eemaldatavalt disketiseadmelt nagu CD-ROM, USB flash drive, või floppy kettalt. NTLDR suudab samuti üles bootida ka mitte NT-l baseeruvaid operatsioonisüsteeme.

NTLDR vajab minimaalselt vähemalt kahte järgnevatest failidest oma tööks:

   * NTLDR, iseennast.
   * boot.ini, mis sisaldab bootimisinfot failis.

Et laadida üles NT-l baseeruvat OS, peab olema fail ntdetect.com samuti olemas olema.

(Fail NTLDR on nõutav. Kui boot.ini on kadunud, siis NTLDR käivitab esmalt C:\Windows kasutas oleva windowsi, teistest läheb mööda.)

NTLDR on kadunud

NTLDR is Missing.
