Hi, this morning, when I was turn on my computer, I get this message:

Booting 'DOS'

rootnoverify(hd0,0)
chainloader +1

Falta NTLDR // Not find NTLDR
Press any key

And My Windows XP failed boot!

Do you know anything about it? How can I resolve the problem? Thanks you!

Good Night! I recovered XP from the problem!
I had to change my boot.ini, copy three or four files from my XP CD.
4 am my boot.ini was misteriously changed by:
OveRaideR Xor_modaL
This was all it contains
Now, when I have my XP working, I see at my DESKTOP: 3 icons:
OverRaider Xor modal
La información
Debe ser libre
¿virus? ¿troyano? I don't know
I only know thath I can't see much of my old icons

Thanks you
