Ntldr don't know what happened but my d drive with my windows xp changed to h
Now when boot it says no ntldr
Need big help

Did you make some type of change to your system that would cause the drive letter assignment to change? This is the root of your problem. Maybe add a drive or remove one, or connect them in a different manner? Possibly add a flash drive or some other removable media? Let us know

Good Luck,

Ntldr is a vital system file that is in windows 2000. It needs to be present for the OS to start.
Try searching for the start up files for windows 2000 online and then either starting with the help of a floppy disk with those files or a USB drive.

Good luck...
