Alright so I downloaded Killbox to elminate a couple of viruses and it worked but in the process I stupidly deleted ntdetect.com. The file was backeduped on Killbox but I didn't know where to send it to so I just left it there and shut down my computer and now when I try to get on it says "NTLDR failed" or something and I can't get on. I don't think I have the windows XP cd for my computer either so if theres any other way of fixing the problem I would love to know.

There are a few ways in which you can recover the said file. You need access to a computer which has a floppy drive and/or a cd burner. You can then download the windows xp boot disks over at microsoft to create boot floppies to use on your system and proceed to the windows recovery console:

Floppy Version:

http://www.microsoft.com/downloads/details...;displaylang=en

Cd Version:

http://www.thecomputerparamedic.com/files/rc.iso (Reference: http://www.bleepingcomputer.com/forums/t/138692/xp-boot-fixes/, usasma's great post! )

Burn iso to cd, using a tool like imgburn.


1. In the recovery console you can select the windows install you would like to fix, should be 1, enter 1 and hit enter, type the administrative password and hit enter.

2. The prompt should show "C:\Windows."

Youll need to know where the ntdetect.com file is stored. Typically it is stored in C:\!Killbox

3. Type "cd "

4. Prompt should reflect where ever the storage location of the file is:

5. Type "copy ntdetect.com C:\"

Additional Info: If youve booted into windows.

The ntdetect.com file is generally located on the root drive. Wherever the windows directory is, its usually the C:\ drive on most typical installs. If you can show all hidden files and folders along with protected system files and do a search for ntdlr youll find where you need to place the ntdetect.com file. You can place the file there and restart the system, however you should attempt to replace the attributes on the file so as to prevent accidental deletion, these are hidden, system and read-only. .

To apply the attributes after youve copied the file over, just type cmd in the run dialog box, hit enter. In the resulting window type C:, followed by "attrib +R +S +H ntdetect.com" without quotation marks.

6. attrib +R +S +H ntdetect.com

Hey thanks so much for your reply sunildev. I followed your link, burnt the fie to a disc and than tried to get into recovery mode. However the computer says "setup did not find any hard disk drives installed in your computer" and won't let me continue. I think the solution involves burning something to a floppy disk and getting into the BIOS(?) but thats just what i've picked up on some other forum postings so I really don't know. Anyways I would truly appreciate any further assistance you can give me. Oh and my computer is an HP Pavilion dv 9000 if thats at all relevant.

Ok.. seems to be a totally different problem than your explaination suggests. Well as you said, you can check the bios to see if the harddrive is listed.. but the fact that the recovery console wont see the drive suggests some sort of harware or hdd corruption issue.

The bios is where we will start first to verify that the computer sees the hdd, from there we can move on. If you need help on this, perhaps you could supply the name of your bios and i will attempt to walk you thru verification.

Alright I pressed f10 on the computer and got to the PhoenixBIOS Setup Utility screen but beyond that I don't know what to look for, just tell me whatever information you need and I'll get back to you with it.
