If you have multiple operating systems installed and properly configured, NTLDR will show a boot menu when your PC 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: NTLDR

"Since I only have one operating system on my Windows XP PC, I never see the NTLDR boot menu."
