Definition: NTLDR (NT Loader) is a small piece of software that's loaded from the volume boot code, part of the volume boot record, which helps your Windows XP operating system start.
NTLDR functions as both a boot manager and a system loader. In operating systems released after Windows XP, BOOTMGR and winload.exe together replace NTLDR.
If you have multiple operating systems installed and properly configured, NTLDR will show a boot menu when your computer starts, allowing you to choose which operating system to start.
A common startup error in Windows XP is the NTLDR is Missing error.
Also Known As: NT Loader
Examples:
"Since I only have one operating system on my Windows XP PC, I never see the NTLDR boot menu."
