Umm, yeah... I started the same thread a few days ago and in the same situation as you. Neither do I had any previous OS installed and recieved this problem...
Are you using another computer to post here?
For me, I can login to my computer if I bootup with the WinXP CD which shows the "Press any key to boot from cd..." message and then not press anything after which then goes to the Windows login screen and not see the "NTLDR file missing, press ctrl + alt + del to restart" screen which just stops there. But this is only a temporary way, of course this is a major hassle to keep putting in the WinXP CD to get in your computer so this is why I too is looking for a solution but it seems nobody is helping or don't know how to fix our version of NTLDR error... :\
If you find a way to fix it, please let me know
