First thing to do is use another computer to download Ubuntu .iso file for your system. You need to burn this .iso file to a cd, insert the burned cd into your inoperative laptop, and run Ubuntu only as a Live CD. Choose "Try Ubuntu without installing" option. This will make your computer think it is running Ubuntu, but no changes to your computer will be made if you do not choose to install it. Any changes will automatically disappear when you shut down your system.
You should be able to backup all your files using this OS.
Direct link to ubuntu .iso file here (version 10.4.4 LTS): http://releases.ubuntu.com/lucid/ubuntu-10.04.4-desktop-i386.iso
No information provided about make, model, or OS so general link also provided here: http://releases.ubuntu.com/lucid/
Other ways to restore the missing ntfs.sys file, so post back asap.

I received an email with a .wav attachment that would not open. So I copied it and pasted it to a MS Office Word blank page and tried to open it. It came form a relative so I thought it was OK.
As soon as I tried to open it a window came up asking if I wanted to "covert" it. I clicked yes and immediately my screen went blue and the following message came up:
Following file is missing or corrupt:
I switched my laptop off and tried to reboot. I got a message "press any key to reboot from CD"
Then the message "You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM. Select "r" at the first screen to start repair
I pressed "r" and the cmputer went into Windows setup. After loading all the files it gave me 3 options
1. Install Windows again and wipe out your files
3. Quit setup
I chose no.2 and it asked me for Administrator Password and although I entered the correct one, it rejected it three times and then rebooted. I tried again and the same happened.
I went into F10 and there under Security it accepted my Administrator Password. I have to save my data because I last did a backup in Nov 2011 so I can't lose anything. What can I do?
