what does this mean "NTLDR is missing"?Do yourself a favor and google for it.

There are 10n results of it.Find another XP computer FULL format a floppy (not to make a bootdisk) and copy the (hidden) ntldr, ntdetect.com and boot.ini files to it.

Put it into your computer's floppy drive and START up.

"NTLDR is missing" can come up for a number of reasons one being if you put a large number of files on the root of C: , namely directly ONTO the C: drive and not in a folder.

It can be corrupted by a virus or just plain damaged.

You need to ensure that the boot.ini file is the same as the one you have on your machine. The standard boot.ini files are...

[boot loader]
timeout=10
default=MULTI(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect

OR...

[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /fastdetect

If you have installed the Recovery Console on your boot drive there will be an additional line...

C:\CMDCONS\BOOTSECT.DAT="Microsoft Windows Recovery Console" /cmdcons

You can easily Edit the boot.ini file with Notepad, if you have to.
